Behind the design

During prototype testing, we noticed that kids just loved playing with the blocks — even when they weren’t fitting them into the sorter. That’s why we made the blocks so big and chunky, so they could function on their own as a block-stacking game. Two ways to play = twice the fun!

    Such a cute toy



    It was a nice toy. But a couple of the shapes could be put in with different orientations. That is not representative of typical cell bindings.



    I really liked the product because it is made out of quality materials-wood, and it makes it fun to learn about different shapes, manual dexterity, hand - eye coordination, and thinking through problems for little ones.



    Loved the large size of the sorter and the blocks. The book is very cute and easy for my 9 month old to follow!



    My daughter absolutely loves this shape sorter. She caught onto the way it works very quickly, although initially had a little trouble with some of the more difficult shapes. She really likes the book as well.



    Great shapes, versatile toy. Book was a bit weak.
