2. Students sharpied over their pencil lines and erased any extra lines.
4. Next, they used white crayon to make lines through the background (we talked about what water looked like in the swimming pool).
5. We used tempera paint in shades of blue to paint over the entire picture, but watercolor would work just as well––if not better. Students had paper towels on hand to wipe off excess paint (If they put it on too thick, their crayon and sharpie lines didn't show through).
