This is a beautifully designed place mat to teach the concepts of shapes and colors. The mat is both extremely basic for very young children and an excellent color-teaching tool for older children. The three primary colors are linked to their respective secondary colors so a child can see that red and yellow combine to make orange, blue and yellow to make green and red and blue to make purple. Each color is shown as a different basic shape. The 11-1/2" x 17-1/2" oval-shaped place mat is hand printed in the USA on thick vinyl.
