from primary till sec school both addition/subtraction i've been taught to do it from right to left.. is way much more easier and faster than left to right ..
Left to right is the way it is taught in hungary & russia (two giants in math). Try doing 342-179 mentally right to left...it would be much harder and impossible for most kids. But doing it left to right is much easier mentally. My 5 year old is able to quickly do this operation mentally because she was only taught the left-right method. Also doing it right to left does not really address place values.
It's interesting. It's like they took the way you would add in your head and do that on paper. They are teaching kids the logic behind the problem. It is much easier to add this way in your head than trying to carry numbers.
You work out mental maths yourself quickly and easily using a variety of mental techniques that do not need to be spelled out, its called logic and MENTAL maths for a reason. As an engineer when I have a piece of paper available, I carry, it's fast and accurate. In fact its made mental maths more confusing and these kids are hitting uni having to be taught maths content. Once you get to higher levels of maths the easy method right to left is the one used. I just accelarated my child through 3 year levels in one year. Guess what he's not held back having to spell out simple logic in a convoluted fashion and can easily complete his work.
Right to left or left to right doesn't matter. What matters most is that the kids understand why they doing what they are doing. I really like the this method bc it incorporates negative numbers earlier so it will definitely be easier later.
It might seem slower but it isn’t, Mentally is faster to go from left to right. . The things is that rn they are young and they write everything but soon they’ll get used to and will start to do it mentally.
The different ways of doing operations is mind blowing yet awesome! Not the usual way of teaching these concepts but would surely reflect the conceptual understanding of the pupils.
To those saying this form of math is slower, it's actually faster to go from left to right mentally, and the impression might be given that it's slower because the numbers and their place values are written out entirely, which is slower and I don't think necessary, (except perhaps at the very levels to clarify the process to students). The two methods written out, (without writing out the numbers in their entirety), are just as fast, but mentally, left-to-right is faster mentally.
This is very new to me. I hope I can learn it now also. That way is like being bilingual in math problem solving. Of course none of us are comfortable with something UNKNOWN, but that doesn't mean is not helpful.
if you want to do addition or subtraction do from the right not from the left because on the right you can cancel. this is how singaporean teachers taught us
I have never seen this method before until now, and this actually seems slower then the normal one I learned in school where we went from right to left?
I do not think the point is speed with this approach. From what I see in the video, the children are using and understanding place value to solve these problems. This way, they are taking a seemingly complex problem and breaking it down into smaller parts, which is a valuable skill when tackling more complex problems. Nobody actually needs to calculate anymore by hand, but everyone does need to know how to solve problems.
Singapore maths is something that is very unique. Problem solving is a method to understand the question and break parts and process it and apply. The answer is not the main objective. So the process is more important then the answer. That is singapore maths. Problem solving is like a story real life problems and examples.
well said,further it encourages the progression and mastery, of provoking kids to think years in advance , 3rd grader thinking like 6th grader an so on.
What level is this method taught? We are doing Singapore 2A (Cavendish) US Edition and this is not the method taught in the book. 2A presents addition/subtraction by doing ones column first, tens next and so on.
JeanLucLittleBear hi. Singaporean student here! I have never learned this method of addition/subtraction. We were taught the normal way of right to left. I was just laughing because this method is just funny to me.
JeanLucLittleBear I agree, I was laughing because I have never seen the methods they used and I was like "my teacher taught me a faster method of addition and all those things, I thought the methods I learnt were slow" :/
Ok but... how does this set them up for higher math? This is based on a visual means, and therefore when students make the transition from the tangible to the intangible, I see that as a problem. In my opinion this completely overcomplicates things and makes a departure from equations which is what the students will use for the rest of their lives.
What are these friendly numbers these kids are talking about?? Singapore method never teaches this way. I would know, I lived through it. We definitely had models but we things that were slightly more difficult than these bc singapore standards.
It's like when the food industry advertizes a new, exciting, rare herb from Farawayastandia that cures cancer, inflamation, etc. They're just calling it "Singapore" to sell a product. In reality, doing math like this stunts the computational process by making it less intuitive. For example, that whole model diagram was painful to watch! 498 + 79 is EASY to calculate! If we want "friendly numbers," it's more efficient to simply add 2 to 498 to get 500, then subtract two from 79 to get 77. Add 500 + 77. How hard is that? They've complicated it. The only accuracy in this whole thing is when they say, "mental math." This is surely mental. --- I get the whole, "we want students to know why" argument. But that's not helpful in most real world scenarios. If knowing HOW the math works is that important, then this sort of thing should be left to specialized math courses that are part of a greater curriculum (necessary for a degree or trade). Most of these kids are just going to be working at jobs where they'll just scan stuff and the computers will do the math for them.
As a chemE and applied mathematics, I do not like this. This method showed be used after they have mastered traditional technical way, esp to check their answer. What happens where they arrive to university? I am curious to see what signapore math looks like when doing algebra
i guess more of us here , who is against the concept we lack the ideal of the methodology, not you only even many teachers , who use the book , but ignore to use the method due to lack of training , they simply opt to use the old school of teaching the way we have been taught or the they way we have been teaching through the years.
I agree with the many commenters who know Singapore Math and know that this is not the least bit representative of Singapore Math. I've been teaching SM grades K-5 for 5 years, all from the original Marshall Cavendish books (Primary Mathematics), and I have never seen most of what's shown here. Shame on Oak Hall School for leaving this up under this title. This is not Singapore Math. Please help people understand Singapore Math by removing this video.
In the 90s we learn to calculate from right to left..This are the new technique they are using now in Singapore...i knew bcoz my children are using this new method here in Singapore.
Dear Mike, i would love if you go listen to the teacher who wrote Marshall Cavendish books, you will be surprised that you are doing it without training hence it defeated the purpose how the books are written, i have long debate with the school/teachers who teach my kids based on this book, i found out that the teacher not even aware there is method called Singapore Math.but the idea is accumulation of set of skills that need to taught from year one understanding of the basic and doing visual math with graphics as well as physical tool especially in grade 1 (the book is showing the tools).if your are using these books to teach, first you need to forget /unlearn the way how you have been taught through the years as well as the way you have been teaching .moreover, the parent also need to be oriented with the method. i believe schools when introducing new books with new methodology they need to train teachers first. i have said the above due to my experience as parent , suffering a lot to get kids getting it right, at the end i have send them KUMON for further tuition , they sound happy now but need some time to catch their grade level. thank you Mike.
@@mohelsad3103 What is the name of the teacher/author you are referring to? Primary Mathematics 2003 U.S. Edition sold by Cavendish was derived with slight modification from the Curriculum Planning & Development Division at the Ministry of Education in Singapore (it states this at the front of every textbook and workbook). The curriculum wasn’t written by one person; it was designed/written by a consortium of experts in the country.
I don’t doubt that Singapore develops very talented math teachers, but Primary Mathematics is not a sacred set of texts as you imply (your quote: “you will be surprised that you are doing it without training hence it defeated the purpose how the books are written”). To this I say: “The proof is in the pudding.” My American home-schooled daughter has comfortably completed ALL the content through 4A. And yes, I know what real math is, even though I’m not a Singapore trained teacher--I’ve taken upper-division university courses in probability theory, abstract algebra and intermediate differential equations. (One of my math professors was even a consultant to the U.S. National Security Agency (aka, The NSA).) Please don’t extrapolate your own negative experience with the curriculum to every non-Singaporean student.
@@sheerylove3437 I’m sorry to hear this! Please consult pre-2003 texts developed by your Ministry of Education to get a handle on good content.

Too complicated. In Vietnam, we do this ex: 924 + 178 From right hand side, add the column 1. 4+8=12 ,separate 12 into 1 and 2 , write down 2 below 1st column , write 1 on top of 2nd column 2. add 1+2+7 = 10 separate 10, write down 0 below 2nd column, write 1 on top of 3rd column 3. add 1+9+1 = 11 write down 11 below 3rd column 11 924 +178 ----------- 1102 THAT's IT!
This method will confuse a lot of children, especially SEN children. Maths has always been taught right to left. I'm sure singapore teaches right to left too. x
i think Math coordinator is from USA. i taught couple of school/college and university in Nepal and also taught school and colleges in USA. I saw a huge math problem because their learning/teaching style is much awkward.
Totally don't understand what these kids were doing that made any sense. Seems like a lot of memorizing and robotics instead of "problem solving." Seems convoluted, to be honest.
I am not sure why they start with left side. But result is the same. Is there a reason to start with the right side? When we do long division we start on the left side. Perhaps one reason students have a problem with long division is, we start with right side for adding, subtracting and multipling. Is it possible to do long division from the right side?

We use carryover to add

Could they not just do the simple way which is more effective and the sums aren’t meant to take a long period.
