What is Singapore Math?

Singapore Math is a general term to describe the math instruction designed by Singapore’s Ministry of Education. In order to prepare for a high quality workforce, the government invested heavily in schools, curriculum research and teacher preparatory. Countries around the world first took notice of the Singapore Math approach when its students topped in international examinations such as the Trends in International Mathematics and Science Study (TIMSS) and Programme for International Student Assessment (PISA) in the 90s. Key strengths of Singapore Math includes logic reasoning, early algebraic thinking, balanced math curriculum, strong visualization, modeling, problem solving and challenging math tasks.

New Location opening in Fall 2022!

My daughter has been fortunate to attend classes since she was in kindergarten. Every year she has loved the classes, her teachers and her classmates. I know Mrs Kar offers world-class math education, and she really cares about providing the very best, from selecting outstanding teachers, to crafting a solid well-rounded curriculum, to caring for and nurturing each and every one of the students, to enriching parents with workshops, and many other wonderful things. My son also joined more recently and he really loves math, his teacher and classmates. Our family is very grateful and we always highly recommend it to other families!
