I used this product with my 9 year old son and he really liked it. He had fun building and comparing numbers. He also enjoyed the challenge cards that have varying degrees of difficulty. I liked that it was a hands-on way to practice learning about place value!

This is a great resource. The questions are varied so many skills are covered. My kiddos find it fun!

Lots of pieces equals lots of lost pieces. Plus it is confusing and boring. but parts of it would work, if one puts away the question cards.
