Primary Maths: Problem Sum Solving with Sakamoto Method

Have you heard of the Sakamoto Method for solving Primary School Maths sums? I have not, so it was a pleasant surprise when I chanced upon it while searching the Internet for Mathematics-related information.

To me, the Sakamoto Method appears to be very interesting, because it takes quite a novel approach to problem solving, employing easy-to-understand logic and simple line diagrams. It’s a bit like Models, but takes it much further without making things mind-boggling.

Note: I don’t know much about the Sakamoto Method yet, but will definitely be doing some research on it. I will report back once I find something more substantial to share.

More About the Sakamoto Method

On the example answer sheet* I found here, it says: “This powerful and easy approach from Japan is applicable for almost all types of word problems, and has been taught at some schools and authorised tuition centres in Singapore for 15 years. In fact, many students use it during the PSLE.” Wow, that’s new to me, certainly.

*The full PDF answer sheet contains worked examples using both Models and Sakamoto Method. Take a look here:

Solving Word Problems

Word problems is another name for problem sums, so called because such Maths questions are usually verbose and stress good understanding of the English language. Mr Kenji Wakabayashi, MD of Sakamoto Educational Systems Pte Ltd, has this to say:

When children are in lower primary, many of them like Mathematics. As problem sums are made of short sentences, they can understand the question and find the answer easily.

When they are promoted to upper primary, however, some students may experience difficulty in problem sum solving, especially in primary 5 and 6… are unable to solve word problems that easily, even though they may have done well in lower primary.

Model drawing is a good way to help them. But sometimes they struggle to draw a model to explain how they get the answer…

Note: Emphasis in above quotation is mine.

Luckily, there’s the Sakamoto Method to save the day. Just take a look at the elegance of this Japanese method in the screenshot below…

Learn Well and Don’t Stop Learning

Learning different approaches to solving Maths problems is a necessary skill that Primary School students need to develop. In fact, having a positive learning attitude from young can lead one to acquire life skills which will continue to serve the person well into adulthood.

It is with this mindset that I embrace the Sakamoto Method and want to find out more, even though I’m not that young anymore. Join me in the discovery of yet another perspective in problem sum solving. I will update everyone as I learn more, for sure (to both actions)!
