Working with wet chalk produces lovely results. Look for chalk that is slim enough for your child to hold it properly or use a lump of chalk that your child can grasp with his or her whole hand.
Presentation: 1. Invite your child to join you for this exercise (pick a quiet time of the day, so that your child does not have to settle down from active play suddenly). 2. Have ready a piece of construction paper or heavy white paper along with a tray that has chalk and a small dish of water. 3. Show your child how to dip the end of the chalk into the water and draw with the wet end.
Your child will see the difference between using the wet and dry ends of the chalk. Remember to sit back and let your child experiment without critiquing or suggesting drawings (or suggesting what his or her drawings look like). The focus should be on the physical movements and motions and your child's development.
