This is a fun project! Choose a set of 3 pieces and then take turns rolling the toy. Whichever side is upright, try to fit your set of pieces into the exposed shape. Every set of 3 pieces, whether grouped by color or by imprinted shapes, will fit into the exposed shapes. There are even two additional combinations of the pieces that will work in all faces of the toy.

It’s based on the book Geometic Magic Squares by Lee C. F. Sallows, and is based on the ancient math puzzle called Magic Squares.
