Color Zoo by Lois Ehlert

This unique book has artfully cut out and overlaid pages that use shapes—rectangles, squares, circles, triangles, ovals, and more—to make the faces of animals. The bright, colorful designs are ones that will keep the children coming back to look again and again. You can extend this to an art activity by having children glue together different shapes—rectangles, squares, hearts, ovals, triangles, rhombuses, and more—to make creations of their own design.
