Color Red and Counting 1-5

I put red food coloring in a glass of water and the kids watched the clear water turn red.

I had them line up and count red Vehicle Counters.

Red play-doh.

I made a red star and numbered the points from 1-5.  Next I numbered clothes pins and they had to match the number clothes pin with the correct number on the point of the star.
