While you are getting your Easter supplies out, give this activity a try....
Fill your plastic eggs with different materials (2 eggs of each material) and try to match them up just by shaking and listening.
I got this package of eggs at the Target dollar spot. I liked that they were striped so B wouldn't get confused and start matching them by color. In the different eggs I put a penny, 2 lima beans, rice, and macaroni. He helped me pick things to fill them with.
It was easier than I thought it was going to be and it was interesting to see how B went about figuring them out. After he played the game twice, he then wanted all of the eggs from his Easter basket out and he started filling them with random things from the playroom which was quite the mess!
