I came across this big bag of shape buttons a couple weeks ago, and I knew I would use them for some sort of bin. But first I decided to use them to make a Shape Sort that also worked on fine motor skills!
I picked out 4 different shapes and hot glued one of each button to a naked puffs container. I purposely chose shapes that had sides and corners, so my little guy would have to look closer at the shape to decide where it went. Then I threw the rest of the buttons (all the shapes) in a bin and set out some little tweezers.
In the end he had a lot of fun sorting the shapes and then dumping them all back together again!
