At what age do they really "do" the shape sorter? DD gets the concept that the shapes are supposed to fit in the holes, but she's a long way off from figuring out which shape goes where. She just randomly shoves any old shape in any old hole.
Edited to fix my speshul morning spelling.
Re: At what age for the shape sorter?
DD has recently starting putting the round circle shape in the proper hole but the other's she can't do yet.
