Our second daughter has begun RightStart Math: A Geometric Approach, and was inspired by Lesson 9, and decided she wasn’t going to be outdone by some kindergartners. She just kept going and ended up with 768 triangles. I’m pretty sure we calculated correctly. I thought you may enjoy seeing her work.
Our youngest began RightStart in kindergarten and finished Level B last year, and he finished up the year testing in the middle of third grade on the WRAT-4.
Thank you for putting this wonderful math program together for our children.
