About Us

Lexington Singapore School offers after-school K-12 math enrichment classes using the Singapore math methods. Besides in-person classes in Massachusetts, we also offer online remote classes.

Curriculum

What is Singapore Math

Singapore Math is a general term to describe the math instruction designed by Singapore’s Ministry of Education. Recent successes in International Mathematics and Science Study (TIMSS) and Program for International Student Assessment (PISA) in 2015 and 2019 demonstrate the effectiveness of the teaching methods.

Strong visualization

One huge appeal of Singapore Math is the use of pictorial representations. Students are introduced to concepts in a three-step approach, Concrete-Pictorial-Abstract (C-P-A) representation.

Problem Solving

At the heart of the mathematics framework from Singapore is problem solving, where students apply higher-order math skills to logic reasoning and challenging problem solving.

Academic Programs

We offer in-person and remote classes for all grade levels year round.
