Easy-Peasy Homemade Scratch Art

I love scratch art paper and was curious to see if I could make my own.  Here's how we did it:

Materials needed:

• white paper (heavy enough to take paint)
• crayons in bright colors (take out the black, brown and dark blues)
• black tempera paint (tip - drop a few drops of dishsoap in it, for some reason it helps)
• paintbrushes or sponge brushes
• wood dowel with a sharp end or toothpick

1. First, have the kids draw a big rectangle on the white paper that fills up almost the whole page. (Having a border will help later, so kids don't paint to the edge of the paper and get paint everywhere)
2. Then, pressing hard color with crayons on the white paper inside the rectangle.  Encourage them to fill up the whole rectangle!  Don't leave ANY white showing!  Suggest to them that they might want to just draw designs or bold strips of color because we will be painting over the crayon. 
3. Next, the kids will paint with black tempera covering their entire colored rectangle!
4. Let dry thoroughly.
5. Last, give the kids their scratching tool and scratch away!
