Third grade worked really hard on their Op Art Paintings. They learned about warm and cool colors and how when placed next to each other they pop out. They learned about the style of Op Art and created a concentric line design. Finally, they placed their hands in their line design to make it more personal. Some were created with tempera, and some were created with sharpie and watercolors. The tempera definately worked better. Some of them were also finished with oil pastels.
