Each shape consists of 2 sides for color and shape matching which helps children learn how to sort and stack the wooden pieces to form a clown. Parents can help children become familiar with shapes and colors by asking them to match the blocks in the correct wooden base. Children learn how to identify colors and sort 5 shapes; square star oval flower and bow-tie. Stacking and matching shapes enhances fine motor skills. I have lots of Plantoys listed if interested in bundling.
