What our parents say

Dear Kar Hwee – I want to let you know how how grateful I am that my daughter is in your math class this year. I have seen a significant improvement in her skill level as well as in her confidence in math. I appreciate the very thoughtful curriculum that supports what she is learning in school and she enjoys your very supportive and engaging style of teaching. When I asked my daughter for a few words on your class she said it was challenging and she gives it 5 stars!! The joy and passion you bring to the classroom is wonderful and my daughter looks forward to class each week! Thank you!

My 1st-grader took his first after-school Singapore Math enrichment class at his elementary school this past winter and absolutely loved it! His instructor, Kar Hwee Koh, presented algebraic problems in the context of colorful animal or alien monster characters that both attracted his attention and kept his focus during the 45-minute class. The exercises were hands-on with many visuals and manipulatives that excited my son and honed his problem-solving skills. I loved the low-key and low pressure atmosphere of the class that also managed to incite his curiosity for more challenging problems. Other than his extreme enjoyment of the class, I loved the take-home explanations of classwork and suggestions for extensions at home. Our entire family enjoyed this first Singapore Math experience and I would highly recommend it to anyone!
