About Singapore Math, Japanese Math, and Lesson Study

comparing and contrasting solution methods area rectangle

Singapore math focuses on problem solving using a concrete to pictorial to abstract approach. Singapore math is famous for the model drawing approach to solving word problems.


Japanese math is based on teaching through problem solving. Lessons typically begin with a problem that students do not know how to solve. Students solve the problem on their own and share their various solution methods, including errors. The methods are then discussed, compared, contrasted and generalized.


Lesson study is a collaborative professional development approach where teachers collaboratively plan, teach, observe and discuss actual classroom lessons.
