Set comes with 10 simple, brightly painted wooden pictures and 30 wooden pieces in 5 shapes and 5 colors. To add color and complete the pictures, children place the appropriate shaped pieces into each of the cutouts. The "form-board" cutouts, keep the shape pieces in place so there is less frustration than with typical pattern blocks. A great learning tool for early development of colors, shapes, and matching skills. Contents store neatly in durable wooden case.
