This is one of my favorite lessons for kindergartners! First, we identify and classify the colors as warm or cool. Then, we choose all the warm colors we have (different shades of oranges, yellows, reds). Then the first day, the paint their whole piece of paper with warm colors. After they have placed these on the drying rack there is usually about 10-15 left of class, so they sketch some dinosaurs from pictures that I have show them. The following class period, they draw their dinosaurs using white colored pencil on a black piece of paper. Then, they cut these out. I show them how to flip the dinosaurs over and glue them down so that their white lines are on the bottom. I love the striking contrast!
