Let students match hearts with each other. First, they have to make their own hearts. The bigger the heart, the better it is for them to handle. Let them decorate their own hearts. When dry, cut the hearts into two using the zigzag pattern. One half of the heart is pinned on a child's shirt and the other half is placed in a bag. Let the students draw out half the heart and find the owner of the half. Once they find the other half, give them a Valentine treat or reward.
