Cut out three different size circles out of white construction paper. On the small circles draw snowman faces, each circle with a different color. On the medium circles draw buttons, each circle with a different color. On each large circle, write out the name of the colors used on the other circles with that color marker. Then cut hats out of different colors of construction paper to match the colors you have used for the snowmen. Glue the hats to the top of the small circles with the matching color. Have the children put the snowmen together, matching up the colors.
