Cut 4 x 4" cards from oaktag or use 3x5" index cards.
Draw a 2 1/2" diameter circle in the center of each card.
Use Skin color paints to color half of the circle, one paint
color on each card. If there are twelve shades of skin tone paints there would be
twelve cards, each with a different color.
Let the paint dry.
Use scissors to cut out the unpainted half of the circle,
creating an opening.
Laminate the cards.
Several Sets of these cards should be available, depending
on class size.
