Add a little art to your math lesson!
I was cutting the ends off large craft sticks to make puppets for another lesson when I noticed the ends looked like ghosts! All the ends were cut one at a time with a pair of scissors. We painted them white to make them look more like ghosts.  After the paint was dry we added ghost faces with a black permanent marker. It was fun to make them all different. We made 20 ghosts. Use the ghosts the way you would use any math manipulatives; add to the group, count, take away, count by groups, subitize, etc.
