Measuring Cups

I found a fun activity for Curious George today. We got out 2 glass bowls and filled one with water and put blue food coloring in it. Then I gave him some measuring spoons and cups and had him measure out the water. He explored things like how many 1/3 cups were in 1 cup, how many tablespoons were in 3/4 cup, etc. He loved it. It worked well because he's old enough that he keeps the water pretty much contained most of the time. If you don't want to use water, you could also let them do it with rice or beans or something. After he got bored with that, I had him stack all the measuring cups from biggest to littlest. That was challenging, but he had fun with it.
