Both my children enjoyed playing with these blocks, they enjoyed playing math games and also making their own games using the numbers and colors. My son is on the autism spectrum and really enjoyed how light weight they are, he could easily pack them up and carry himself as he prefers to do things independently. He was able to easily count on the blocks and focus on the numbers and colors, he has not gotten bored as the blocks are versatile. He has even made his own learning games using the blocks stacking function and numbers on the blocks. We are so happy with this product!
