Are binary options reliably 4th grade

Reliably Finding Strong Price Levels to Trade. The European session opened up with a decent amout of volatility on the GBPJPY, with large wicks on the opening candles spanning over fifteen pips. The market first rose up to the daily pivot level of 172.264 although no trade set up in the way in which I approach the markets, given the close above the level. The pivot did eventually hold and on the way down I began targeting 172.100 as a support level for call options. In the image below, you can basically observe why I had this level marked off as having trade potential. There were basically three prior instances within the past few hours that had supported 172.100 as a support level. And on all three occasions it had acted as a shelf for price to rest on. Of course, I needed some sort of price action confirmation for me to get into a call option. I never trade just the level itself, as it’s too risky. Support and resistance by itself in isolated form isn’t a great methodsystem to trade, even if you’re targeting major levels only like pivot points and the one seen here created from previous price history. It’s important to consider the price action, as well, in addition to trend and momentum, most notably. The 4:10(AM EST) candlestick did bounce off 172.100, as did the 4:20 candle. The case of two five-minute candles showing rejection gave me enough confidence in looking at getting into a call option on the next touch of 172.100. Oftentimes, in the case I’m considering a trade against a recent trend or bout of movement contrary to the direction of my intended trade, I’ll look at more than one rejection (confirmation) candle to help validate its robustness as a price level worthy of trading. As such, this is what I did here.

I got into a call option on the touch of 172.100 on the 4:25 candle. This trade did spend a decent amount of time against me, going two pips out of favor before rising a pip in favor. In the end, I wound up with a two-tenths of a pip winner. This is a slim margin indeed, and one could definitely say some luck was involved. Nevertheless, the general prediction that price would hold on the fourth consecutive test of 172.100 did come to fruition and price began to break higher again just after 5AM EST. Pivot re-established itself as a resistance level on the 5:20 and 5:25 candles, neatly closing and opening at the level and rejecting further upward movement. The bearish 5:30 candle was exactly what I was looking for in terms of showing that selling movement was in play. It’s really exactly what you might want to see at a resistance level when you’re considering a put option set-up. After all, if you’re considering a put option trade, you might want to actually observe some sort of selling tendency in the market first as evidence supporting that position. The 5:35 candle did not touch the pivot level, but the 5:40 did where I got into a put option at 172.264. This produced another rejection initially, but buying movement continued afterwards and I lost this trade by a couple pips.

The market would hang around pivot until around 7AM, although no real call option opportunities emerged. Given the uptrend all the way from 172.100 and through the pivot, it wasn’t entirely surprising that resistance 1 (172.435) was the next level in sight. And like the pivot level in the previous trade set-up, the price action around resistance 1 was similar. Price rejected 172.435 on the 7:25 candle, held below on the 7:30 (reaching five pips below resistance 1 at one point), before coming up to reject again on the 7:35. Like previously, I waited for this second rejection of the level to help validate that price as a solid area for reversal, given I was up against an uptrend. After the second rejection, I looked to get into a put option on the next touch of 172.435, which occurred on the 7:40 candle. This trade spent a little time out-of-the-money, but by no more than a pip or so, before going up to five pips in favor, before closing as a three-pip winner. This level did hold, so I could also feel good about the overall idea behind the trade and my reading behind the market. RSI Indicator. Technical RSI indicator is indispensable trader’s tool. This oscillator widely used in the whole world in its standard form as well as in different modifications.

Binary options trading is not any exception, and traders also tend to use RSI indicator a great deal in their strategies. Oscillator can be indispensable in situations, where it is necessary to spot very strong trend on which one can earn well on false impulses. It is also often used to filter out the false signals of other indicators. Relative Strength Index was elaborated by J. Welles Wilder in 1978. Author even wrote book about RSI indicator named as «New Concepts of Technical Trading Systems». Oscillator yielded strong popularity among traders not long before the book was released, and it still is very popular as well. This indicator shows the amplitude of price movements on chosen asset. In other words, RSI defines how strong the trend or its potential is now. In chart, it is shown in separate window by means of the one line with the values varying from 0 up to 100: Low values signify weakness of bears while high ones imply weakness of bulls. RSI indicator is calculated using the following formula: RSI = 100 – 100 (1 + RS), where RS = average growth average fall. When the average growth value is greater than the average fall value, then the indicator line is going up. The same situation is observed in case of the line going down: the average fall value exceeds the average growth value.

The benefit of this indicator implies range varying from0 up to 100. Choosing the zones in which the asset will be considered overbought or oversold will provide an excellent advantage in binary options trading. The RSI inventor recommends to distinguish the levels 70 and 30. When the line is above the level 70, then it means that the asset is overbought, which in turn will result in reversal or delay of the upward trend. If the level value is below 30, then one should expect reversal of the downward trend or its transition to flat. The Ways to Use This Indicator. Using Relative Strength Index in binary options trading, one can get quite many different signals. The most popular approach to using RSI is trading on corrections and reversals, that is, when the line is located in the overbuying or overselling zone. Using this approach, one should close a deal only when line crosses bask one of the level and gets fixed by closure of one candle as follows: Using the line pullbacks up to the certain levels is also quite a common phenomenon. It also works at conventional horizontal support and resistance levels: Both these methods work well at the flat time. However, when there is some trend movement in the market, then indicator might give a great deal of the false signals. Exit from the overbuying or overselling zone quite frequently shows only deceleration instead of beginning correction or reversal. In order to distinguish when RSI signifies deceleration or beginning of more important pullback, two states of overbuying and overselling were introduced as follows: Extremal overbuyingoverselling states imply crossings along five or more bars. Moderate state implies the presence of a line beyond the levels in period of less than five bars.

When the moderate state takes place, reversals and corrections happen much more often. When the extremal state is present, trend often slows down: Buying options in presence of moderate overbuying or overselling states only, one can catch stronger movements and earn much more money as a result. RSI oscillator can also be used to spot divergence: The signal is considered good when the divergence has formed along with exit from overbuying or overselling zone. Technical RSI indicator is an excellent and sometimes indispensable tool in binary options trading. Therefore, every trader should master its use. However, despite of the all seeming advantages this indicator possesses, it is wise to use it in combination with other trend indicators such as moving averages, Bollinger bands etc. when elaborating trading method.

If you want to trade consistently and profitably at binary options, then you’re going to need to choose to do things differently than other traders. The vast majority of binary options traders will lose money overall and never become profitable in their trading, but that is because they are not going to use consistency in their trading methods. If you don’t apply consistency, how can you expect consistent profitability as a result? The cards are stacked against you in binary options trading. If you don’t take the extra steps to become profitable the odds are you are going to lose money. We’ve put together some helpful binary trading rules to get you started on the path to greater consistency.

Rule 1: If you want to profit consistently, you need to come up with rules that you understand. Rules are what separates your trading method from trading methods which lack consistency. They give you something concrete that you can stick to when things get confusing, which often happens while you’re trading. There are many types of trade rules that you’ll need to incorporate into your trading method: entry and exit rules, money management rules, rules of discipline. It’s not enough to just have rules, either you need to learn to understand how and why they work. This will help you out the day they stop working the way you think they should. All trading methods fail sooner or later, but not necessarily permanently. When that day comes, your temptation is going to be to go back to the drawing board and start all over, but more often the best choice is to stick with your trading method but make adjustments. If you understand why your trade rules worked when they did, you may have a better chance at understanding why they’ve stopped working in the time since. This can help you to make the proper adjustments more quickly and get back on the path to profit. Rule 2: You need to actually follow the rules you come up with. Consistency isn’t just about having a great plan, it’s also about follow-through , which for most of us is a lot harder than coming up with the initial plan.

Planning takes hard work, but application takes consistent hard work over a long time period. It involves dealing with discouragement, frustration, anger, boredom, and loss in a levelheaded way. You can’t completely divest all emotions when you’re trading you’re only human. But you will have to learn how to deal constructively with those emotions and mitigate the effect they have on your trading. Negative and positive emotions both can mess with your trading plan if you let them. You’ll need to develop the discipline to apply your rules every time and without exception. That doesn’t mean you can’t use your discretion when you apply them, but that discretion, like everything else, needs some basis in concrete theory and testing. It can never be random. Rule 3: You need to accept the changing nature of the market. Trading well is all about removing as much randomness from your trading as you can by removing randomness from yourself and your actions. While doing this can reduce your risk and make it far more likely that you’ll be successful with your trades, one thing you can never do is have the pride or ignorance of assuming you’ve discovered the perfect, infallible system.

All systems have flaws, and many are exposed only with time and change. There are many patterns in market movements, but over time there are shifts that gradually may erode at your profits. You can liken this to climate change. It’s relatively easy to predict the weather in a given area once you’ve learned the weather patterns, but it’s much harder to get a clear vision of long-term climate change and how it can impact life in the future. Market climate change can break a good trading method. If the market changes and you don’t, you’ll find a once profitable trading method no longer works, no matter how consistent you are. This is the point at which you have to adapt your trading method to the new market conditions. Understanding why your method worked will help you do this. No trader gets out of having to do this. Once you do adapt to the new market conditions and your method works once again, you again must follow your new, adjusted rules with discipline in order to succeed at binary options trading. 5 Binary Options Rules Not To Break. If you’re getting into binary options trading, you probably have heard that you should find ways to be consistent in your trading. Trading with discipline helps you to filter through the randomness of the market to find consistently profitable trading opportunities—and to come out of those opportunities ahead.

You may also have heard though that there’s nothing wrong with trading with your discretion. Discretionary trading is contrasted with mechanical trading, where rules are followed exactly without deviation. If you’re thinking of discretionary trading, you may wonder which rules you can bend, which you can break, and which you should never violate. What are five rules that binary options traders should never break? The amount of money you risk on each trade, as a percentage of your trading bankroll. You should never trade 2.5% of your account and then suddenly think, “That’s a great looking setup. Just this once, I’m going to invest 10%.” Start breaking this rule and you won’t stop. Next it’ll be, “I lost 10% on my last trade, but this one can really turn it around, but only if I invest 10% again. Or let’s make it 15%.” See how quickly this can blow your account? Always risk the same percentage.

As your account grows, the dollar amount will grow with it, but the percentage must stay the same. Feel free to use rollover or double up if a trade is going your way, but only if you’ve figured out a consistent approach to using it which results reliably in profit every time. Account exposure. Just as there should be a maximum amount you’re willing to risk on each trade, there should be a cap on the total amount you’re willing to risk at once. This is referred to as your “exposure” across all your trades. So you might have a rule like, “I’ll only ever invest 2.5% of my account per trade, and only enter up to 3 trades at a time.” Entry and exit rules. You don’t have to take every setup you see, but you do need consistent entry rules and a thorough understanding of context for your setups. You can’t start doing this: “I don’t have much of a setup here, but I am so sure that the price of oil is going to rise, so I’ll enter.” You also can’t start doing this: “My exit rules tell me a trade no longer exists and I should get out, but I really want to with my money back so I’m going to stay in instead of using early closure.” This sort of thing will lose you money.

Testing requirements. You should never go live with a new trading method or an adjustment to a method without testing it first. Optimally, this should include backtesting on historical data and demo testing with virtual money. If your method needs adjusting and isn’t profiting anymore, don’t start making arbitrary changes and testing them with real currency. Instead, make the adjustments on paper and test the changes to see if they will improve your performance before you risk real money on them. Honesty. The number one rule you should never break is your honesty to yourself. The moment you compromise on that, you have no hope of following the other very important rules listed here. How do you account for these unbreakable rules in a discretionary trading setup? Think about your trading as including different “rule profiles” for different possible situations.

Your trade amounts and account exposure should never differ, but you might have different sets of entry and exit rules based on different possibilities. So a rule that would apply in one trading context might not apply in another—but the context-based rule governing both provides you with consistency. The last two rules should also never be broken. Good luck with your trading, and try to trade with a broker which provides you with demo testing capabilities! NOTICE.

With binary options trading becoming overwhelmingly popular, it is expected to see a boom in the amount of automated trading systems available online.

Sadly, there are a lot of dishonest and shady people out there that are taking advantage of this fact by trying to scam innocent and unsuspecting traders out of thousands of dollars. This is why we recommend that you read as many reviews about a trading system as you can before opening an account. Binary Pot of Gold has recently emerged and promises its traders substantial profits in just days. Can they be trusted with our money or is this just another shady con? Read our Binary Pot of Gold review to find out more. Fully automated System is easy to use for new traders. Website is poorly designed and does not provide company details No option to choose your own broker Brokers are not regulated Endless online complaints from traders who have lost all of their investment. What Is Binary Pot of Gold ? Binary Pot of Gold is a fully automated trading system created by James Tanaka and Russell Cargill, founders of the Tanaka Cargill Group. Of course with a name like that, one would think that they are indeed a legitimate company, right? However, during our Binary Pot of Gold investigation, we discovered that there is no such company under that name. We also determined that both James Tanaka and Russell Cargill are made up names, as we could not find any concrete information on them to prove that they are, in fact, real people. Also, the website is poorly designed and offers no company information, customer support details or insight into how Binary Pot of Gold actually works.

We find the lack of information very disturbing and therefore from the very start of our investigation we did not have a good feeling about this trading robot. How Does It Work? To gain access to Binary Pot of Gold trading software, you must create an account, register with a predetermined broker and fund your account with $300 before you can trade with the system. We found this to be a little high, as the norm is around $250. Also, we do not like the fact that you are not able to use the broker of your choice, rather you are forced to sign with one of the broker’s associated with Binary Pot of Gold. And much to our dismay, we discovered during our trial of the system that none of their brokers are regulated. IF a broker does not have to answer to a regulatory body that oversees their policies, there are often loopholes and traders end up losing thousands of dollars without a legal leg on which to stand. Therefore, we do not trust this trading system. During our initial review, we searched offsite for customer reviews and found nothing but complaints about traders who lost all of their money and were unable to regain access to their trading account. As well, they could not get a hold of customer support to question as to what happened to their funds.

We feel this is highly unacceptable and cannot stand behind Binary Pot of Gold as a reputable trading system. Conclusion: Is Binary Pot of Gold a Scam ? After a detailed investigation into Binary Pot of Gold, we cannot in good faith recommend this service to our faithful readers. We feel that the lack of unbiased reviews, as well as the numerous complaints about the system, is enough to deter us from referring anyone to this service. While we cannot determine at this time if it is indeed a scam, we do not suggest taking a change with Binary Pot of Gold. We advise that you sign up with a trading system that has proven success.

I wanted to build on my prior visit, where I introduced them to the powers of two. By teaching them binary, I showed them that place value is not limited to base ten, and that there is a difference between numbers and numerals. My presentation was based on base-ten-block-like imagery, since I knew the students were comfortable expressing numbers with base ten blocks. I thought extending the block model to other bases would work well. I think it did. The Number Twenty-Seven in Tape Flags, Broken Into Powers of Two. Before my presentation, I put twenty-seven tape flags on the whiteboard, in an unorganized fashion like this: (I would have preferred to use magnets instead of tape flags, since they would have been easier to move and align but I didn’t have twenty-seven identical magnets.) I started my presentation by telling the class that I would teach them about something called binary numbers, but that first I would review the numbers they already know — decimal numbers (I took a moment to explain that this was not the same as &ldquodecimals&rdquo). The first thing we did was count the tape flags, and as we counted together I rearranged them into a line: Twenty-Seven Objects, Arranged In a Line. I asked them how they would write that number.

One student came up and wrote &ldquo27,&rdquo which is the first answer I expected. Other suggestions were Roman numerals (&ldquoXXVII&rdquo) and &ldquotwenty-seven,&rdquo also as I anticipated. One student suggested writing it in Japanese (I was expecting a foreign language, but Spanish: &ldquoveintisiete&rdquo). Some students suggested arithmetic expressions, like 20 + 7. One unexpected answer was from a girl who wrote it on the board in base ten blocks, which is how I was planning to rearrange the tape flags next! I suggested tally marks as another alternative, and wrote twenty-seven in tally marks on the board. I singled-out the answer &ldquo27&rdquo and said it is written in place value. I reviewed how the places were powers of ten. Then, as the class counted along to twenty-seven, I rearranged the flags into base ten block powers of ten groups, under headings labeled &ldquotens&rdquo and &ldquoones&rdquo: Twenty-Seven Objects, Broken Into Powers of Ten. We counted the powers of ten and wrote the totals in the blanks I drew below each grouping of blocks we came up with the numeral &ldquo27&rdquo: two tens and seven ones. I told the class that place value is not limited to base ten.

I said, for example, you could write any number in base five, or quinary. (I wanted to take an intermediate step to binary, which is the simplest base, having only a maximum of one instance of each power.) I had them compute the powers of five from one to 625, and I explained that these are the places in quinary. I told them we would group the flags into powers of five. I wrote three headings on the board: &ldquotwenty-fives,&rdquo &ldquofives,&rdquo and &ldquoones.&rdquo I asked &ldquoare there any twenty-fives in twenty-seven&rdquo and they said &ldquoyes.&rdquo We then counted out twenty-five flags, which I removed from the decimal grouping we’d just done. I built a block as we went, under the twenty-five label. Next I asked if there were any more twenty-fives in the flags that remained, and they quickly said &ldquono.&rdquo They could also see there were no fives, and that there were only two ones left, which I moved under the ones label. Twenty-Seven Objects, Broken Into Powers of Five. We counted the powers of five and wrote them under each grouping of blocks, coming up with the numeral &ldquo102&rdquo: one twenty-five, zero fives, and two ones. Some kids wanted to pronounce this as &ldquoone-hundred and two&rdquo, but I told them you pronounce it as &ldquotwenty-seven,&rdquo or &ldquoone-zero-two base five.&rdquo Now I said let’s look at another example of place value: base two, or binary.

I said it is based on powers of two. We computed the powers of two from one to thirty-two (my son was rattling them off to 4096 before I could cut him off :)), which they remembered from my last visit. We proceeded as above, except we pulled out the powers of two (from the flags in the quinary grouping): first we looked for sixteens, then eights, then fours, then twos, and then ones. Twenty-Seven Objects, Broken Into Powers of Two. We counted the powers of two and wrote them under each label, coming up with the numeral “11011”: one sixteen, one eight, zero fours, one two, and one one. When I was done with the tape flag examples, I took a moment to explain that base ten has ten digits, base five has five digits, and base two has two digits. As an example, I said that in base ten you could never have a 10 in any place, because that would be the same as a 1 in the next higher place. Similarly for base two, a 2 in a place would equal the next higher power of two, which also would be the same as a 1 in the next higher place. I told the class that you could write any whole number in any base. One kid asked if I could do it in a base that was greater than ten (I forget which base he used as an example). I said any number could be the base, but you’d have to have enough symbols. I briefly explained why you wouldn’t want a multi-digit number in a place (it would make the numeral ambiguous). I mentioned base sixteen, and said it uses the letters A through F for the values ten through fifteen.

(I did not intend to get into hexadecimal, but hey, I wanted to answer the question!) Students as Binary Numbers. At the front of the classroom, just below the whiteboard, I arranged five chairs, facing the class. I wrote the names of the binary places above the chairs, left to right from the class’s point of view: sixteens, eights, fours, twos, ones. I got five volunteers to come up, and said that I would turn them into a binary number. I said if I told them to sit in their chair, they would count as a 0 if I told them to stand in front of their chair, they would count as a 1. For my first example, I put the students in the pattern 11011, which the class correctly read as twenty-seven (they added the place values above the chairs of the standing students — that or they read the numerals I had left on the board under the tape flags :)). I did a few other examples like this, which amounted to binary to decimal conversion. They got them all right. Next I did what amounted to decimal to binary conversion, asking the class how to arrange the volunteers to represent a given number. For example, when I said &ldquonine,&rdquo they called out instructions to make the volunteers stand and sit to make the pattern 1001. They got all of these examples correct as well. The above discussion took about twenty-five minutes, so with the extra five minutes I squeezed in a demonstration of a binary counter.

I took a new set of five volunteers and had the class direct them through the sequence zero to thirty-one. We got through the count, but I think a few students got lost as some of the faster adders called out instructions. In any case, there were definitely some who understood the process, enough to know that when I asked them to display thirty-two, they said we would need another volunteer. If I had more time, I would have done the count a second time, with the volunteers driving the counting I came up with this scheme after I left the class: All volunteers start out sitting, representing zero. Whenever I say &ldquocount&rdquo The ones place volunteer does the opposite of what she is currently doing: if she’s sitting, she stands if she’s standing, she sits. For everyone not in the ones place, if the kid to your left sits, you do the opposite of what you’re currently doing. I think this would have made the counting easier and more fun. ( Update 11712 : I gave this presentation again recently — to fifth graders — using the new counting scheme. It did not go over like I imagined. The kids were confused about when to stand and sit, and weren’t having fun. In the future, I’d omit binary counting in hindsight, it seems too &ldquocomputery&rdquo for this context.) I mentioned briefly that there is an equivalent of decimals in binary numbers. Instead of the tenths, hundredths, etc. places there are the halves, quarters, eighths, etc.

places. I think most of the kids understood the presentation certainly, they were all engaged. I’d like to think it gave them a better understanding of decimal, even if they didn’t understand the details of binary. I told them &ldquoyou may not understand this now, but when you see it again someday, you’ll remember back to this day in third grade and it will come to you.&rdquo Someone then asked what grade they teach this in. I said it’s not really part of any particular math class (as far as I know) but that they would be taught it in a high-school computer class if they took one. I used number words when I wanted to avoid writing decimal numerals for example, when describing a number or when labeling places. Unfortunately, number words have decimal place value built-in, but that’s the closest I know how to get to a base-independent description of a number. That said, I don’t think the class recognized this, so I don’t think it caused any confusion. I didn’t explain why we broke the numbers down by starting with the largest powers and working down. If I had more time, maybe I would have let them discover the algorithm themselves.

I use the term &ldquonumber&rdquo when I really mean &ldquonumeral&rdquo, as in &ldquobinary number&rdquo or &ldquodecimal number.&rdquo This terminology is unfortunate, but it is standard. I used a different approach, but a lot of the same concepts are involved. Rick’s method centered on binary counting, which lead to a discussion of powers and places. My method started with powers and places, and lead to binary numerals and then binary counting. Rick discussed other bases after discussing binary, whereas I discussed them before. Also, he discussed binary arithmetic, but I did not. One thing I liked about my approach is that I built in the concept of base conversion, showing the equivalence of whole numbers written in any base. I also liked the way I exhibited the concept of &ldquonumber vs. numeration.&rdquo This page contains videos on binary counting, which inspired my own binary counting demonstration. I taught my mother a little differently (at least in my second attempt), mainly because I think most adults don’t think explicitly about place value. I’d love to know if this method works for you if you try it, please let me know!

22 comments. What an awesome idea! What is a way they could utilize what they learned right after you teach them? Is there something online? This is awesome. I teach 3rd grade math at an NGO in Brazil and will give this a try if I can! There is no applet online that I know of that presents you with a collection of objects and lets you rearrange them by base (sounds like a good project for one of my readers 🙂 ). As for general practice with binarydecimal conversion, check out the Cisco Binary Game. Thanks for the feedback. Good for you. Working with young people is really a treat. We have been teaching binary numbers and C programming to 7 & 8 year olds for a while. They are really easy to work with when the good teacher is at ease with the topic.

In reading what you have done I get that you are at ease. All the math I learned in school was due to the comfortable teachers I had. The two that I got not from were definitely out of their league. Keep up the good work. I like it… and learned a couple of things! One thing that got me confused is that the “Ones” columnposition has more than one block per column, you have to count them vertically, on the other columns you can count horizontally. I dug up my son’s old “Growing with Mathematics” workbooks to see how they do it (maybe I should have done that in the first place instead of relying on memory?). They place the ones both vertically and horizontally, so I don’t think that’s the problem. (I don’t think strict adherence to either vertical or horizontal placement necessarily scales to higher places — and higher bases — anyhow.) They key thing I think they do though is put more space between the ones blocks. As is, mine looks like an incomplete rod I can see why that is confusing.

Here’s how I would redo the decimal diagram, for example, in Growing with Mathematics style: Do you think that works better? Thanks for the feedback! I’ve learned another activity for students to be active participants in there learning process. Thanks! I also taught Binary to third graders. I had them sort blue and white mancala beads into as many patterns as they could using exactly 4 beads (blue blue white white, blue white blue white, etc). Used the smartboard to further examine patterns in binary numbers. Brought in the binary clock – big hit. This was an enrichment lesson during my time unit. Kudos for thinking outside the box 🙂 That sounds like a good exercise. Did any of them figure out a systematic way to do it (wwww, wwwb, wwbw, wwbb, wbww, etc.) before you told them about the binary patterns? I thought about bringing in my binary clock too — but I’ll be sure to do it next time. Thanks for the feedback.

I hope some of you who are interested in teaching children about binary will have a look at funforms, a place order, binary, tally mark system. A narrated power point presentation is available at. It’s nice to see someone who’s been thinking of binary numbers almost as long as I have :). An interesting article. I tried to teach different base counting to a group of year 4’s to support their learning of 5 digit numbers and what the columns actually mean. I ran out of time to get to binary. I had played with 21 as a number and had groups using connectable cubes so they could easily group. I’d love to take it the other way and look at hexadecimal. I wonder if it would be possible to then look at how drawing software adjusts (mixes, averages, subtracts) colours depending on brush options. Do you know if it would facilitate the comprehension of numbers to a children by teaching them first binary (around 4 years old) and then teaching them decimal (around 5 years old). I mean… do you think a young child could process and understand the basics of it? (for example you put 4 bananas on a table and ask him how many there are… then you tell him there is 100 and then count with him: 1-10-11-100!) because if a five years old child could understand those basics, a few years later he could even be able to count, addsubstract, multiplydivide and even exponentiate mentally more than anyone! My point is that math is a language in the same way that English is one and if children could be mathematically bilingual the same way he could be directly, his mathematical development could be insanely boosted!

I agree that it is like a second language, but only to a point. Unfortunately, we don’t have words for binary numerals. We pronounce 101 as “one-zero-one”, not as something like “four and one” (or something totally new and not decimal number word based). That said, I think there is great value in introducing another base, though probably after base ten. Like learning a second language makes you understand language better, learning another base will make you understand numbers better. Then how about *inventing* systematic names for binary numerals, in the same way we invented the decimal ones? Here’s my proposition, from the top of my head: Let’s say, we can read 10110 as deedodeedeedot :)The pattern is simple: 1 is the “dee” sylable, 0 is the “do” syllable. The ending “t” (unvoiced “d”) is just to mark the least significant digit, so that we can also express fractions this way: 101.001 is deedodeetododee. Or we could also stick with the unvoiced consonant for all the fractions to make deedodeetototee. Although this is quite easy to readpronounce, it is no longer easy to write, because the names get long. So I think a better option could be to something more compact, where we would not waste more letters than needed. The simplest conversion (a direct one) would be to replace every 𔄘” with one letter, and every 𔄙” with another, but there is a tiiiiny problem with it: consecutive 0s or 1s would then melt together in speech, making it difficult to distinguish how many of them is there 😛 Therefore we need to use syllables anyway, made of two letters: a consonant and a wovel. So we need at least *two* letters for each binary digit, which is not as compact as the binary numeral itself, but it is the best we can do, I guess.

To make it less repetitive and easier to distinguish, we can use a different wovel for 𔄘” and different for 𔄙”, and the same goes with the consonants. In my native language, we pronounce the letter “i” as the English “ee”, so the notation is quite space-efficient and easy to pronounce & distinguish from hearing. If we wanted something more compact, we could also try to join consecutive digits of the same kind somehow into one syllable, in groups of two, three etc., by changing the consonant that goes with it. One possible code could be: So now we can name numbers more efficiently 😉 almost like abbreviating them through tetral and octal 😉 Some examples: So we can see that the more digits repeat, the more space we can save through this “run-length encoding” scheme 🙂 Another possibility for the RLE is to double the number of repeating digits with each new code, which should make it even more space efficient in the long run (no pun intended, but appreciated 😉 ). I guess this could also facilitate mental calculations. To facilitate learning this code, you can make diagrams like this one: 111 00 1 0000 1. and after a while your brain should pick up these syllables along with their corresponding bit sequences pretty quick 😉 For longer or more sparse numbers, like 0.000000000000000000001, it could become cumbersome to write down or pronounce them (sasasasati) 😛 so we can introduce something similar to the scientific (exponential IEEE) notation by stating the mantissa and the exponent separated by some unique letter, let’s say “r”. Then, for the long number above, we can simply write down pronounce the scale first (because it tells the most), then saywrite “r”, and then write down pronounce only the significant digits (𔄙” in this case), which gives: titatitatardi (1×2^-10100 in binary, or 1×2^-20 in decimal). The system is so simple that I think it could be easily taught to a kid even before the decimal system (except the exponential notation, which could come later). Have always been interested in teaching kids about ‘numbers to other bases’! I think introducing binary, then hex, up front is helpful..since it quickly sends. out the idea of number bases with other than 10 numerals? Then you can get right into it by showing how each 4 bit binary segment of a 16 bit binary word equates to each single hex digit of a 4 digit hex word: 1111 1011 0111 1001. etc…this is solid computer lingo!

I’m in the process of compiling computer science lessons for teachers, and your lesson really helped me clarify language and methodology that children will understand. Thank you so much for sharing! I’m glad it was helpful. This is some much more interesting and simpler than the lesson we use on our computer class with our 5th graders. They glaze over after 10 minutes. I was looking for more interesting material for them. I will definitely try this this year. This looks amazing! I teach Engineering and Technology to 1-4th grades, and I definitely love the idea of this for my 3rd and 4th graders! Does anyone have any ideas for how to introduce this to 1st and 2nd (my biggest concern is that their multiplication skills aren’t the strongest, or nonexistent at that age). I read a book to first graders that was about the powers of two, although it was not stated in those terms. Maybe you could start there. Leave a Reply Cancel reply.
