After School Singapore Math Classes

Small Group Classes based on the Singapore math curriculum

Balanced and Rigorous Curriculum

Why Singapore Math

We adopt a balanced math curriculum based on the Concrete-Pictorial-Abstract Singapore math pedagogy. Using strong visualization and modeling, we emphasize Logic Reasoning, Early Algebraic Thinking, and Problem Solving. Our goal is to establish a strong mathematical foundation in our students so that they would enjoy challenging math tasks.

Concrete

Abstract concept is first introduced using physical, interactive concrete objects, e.g. counting objects

Pictorial

Students use visual representations of concrete objects to model problems, making them easier to comprehend

Abstract

Students understand concepts at a symbolic level, e.g. using symbols for mathematical operations and algebra

Congratulations to our students on their fine achievement in the CML 2020-2021

Our Grade 4, 5, 6 and 9 teams are Regional Winners in the CML 2020-2021 competition season! Massachusetts is in Region 1, which is our New England region. It includes: CT, MA, ME, NH, VT, RI.

Lesson Structure

Each week’s lesson consists of two parts:

Foundational Math

Focus on conceptual understanding and procedural fluency. Topics are taught linearly and circled back the next year, promoting deeper understanding.

Problem Solving

Students are exposed to unfamiliar problems every week, requiring them to deeply comprehend the problems and organize to problem-solve.

For my son, the additional reinforcement of math principles that Singapore Math is so important for his memory, processing ability, and math confidence. Ms. Jean is a terrific teachers who my son both respects and genuinely enjoys learning from. I wish she was in his classroom every day!

– Parent of 2nd Grader

We like the small class size, and teachers providing feedback about my child when necessary especially when I can also help, CML problems and meets, the active involvement of the owner Kar Hwee, which has maintained and improved the quality of instruction over the years!

– Parent of 4th and 7th Graders

Love the practical application of math in the problems presented. It’s not just about learning how to compute a calculation, but how to think through what the word problem is asking and how to apply math (and which tools) to the solution.

– Parent of 6th Grader

Our Journey

Our program started in 2015 in our dining room. Over the years, we have build a strong team of teachers and have helped many students build strong mathematical foundation and learn to enjoy math.
