This takes the student beyond simple visual, they are involved. I see more thinking and better results.

This is an excellent hands on product for prime factorization, but I am not pleased with the quality of the material. I couldn't find the material description on the product page before purchasing, so I did not know this item was made of foam. Foam just doesn't have the longevity and durability that I was looking for in a product like this. A product that will be used multiple times by multiply students for multiple years. I would have given this product five stars if it was made from plastic or wood. I definitely would not pay full price for this item, I'd wait for it to go on sale.
