4th Grade "Batik" Pumpkins

My 4th grade students are currently learning about value. Right now, we are mixing different tints and shades with tempera (I'll post about it in a few weeks). Last month, I introduced the concept, and we made value pumpkins with crayons. The students used different values of orange to make the pumpkins look round. Then, we wrinkled them up (the kids loved that part!), smoothed them out, and painted over the whole picture with watered down black tempera paint. We dabbed the pumpkins clean with paper towels (it was messy!) and here are a few of the finished results. Some students colored the background as well, but I forgot to take pictures before they took them home:
