I love this product! My little learners often struggle with maintaining focus when provided/working with small manipulatives such as counting squares/bears, unifix cubes, base ten blocks. These self contained manipulatives are fantastic for illustrating subitizing within 10 WITHOUT all the pieces falling off tables/desks or being built into other things. The odd numbers are red and the even are blue which is a nice touch for differentiating between odd/even as well.
