Draw a clothesline across a sheet of paper with clothes hanging from it. Give your children ten clothespins each. Have them to hang up some clothes using four clothespins (they will place the four clothespins on the paper). Then have them hang up some more using five clothespins. Ask them how many clothspins they used. (They just added) Ask them how many are left. (They just subtracted)
