Richie matching shapes on Anpanman ball

Richie is 16 months old now. He has become very active and interactive too. He has an Anpanman (Japanese cartoon) ball having various shapes cut out on it. It has dual purpose. He can play it like a ball by rolling it or match the shapes with different colors.He started to match the shapes one-by-one. Some seemed pretty easy like circle,ellipse, but some others were a little difficult at first. Though we taught him a few first, he managed matching the rest himself with ease.
