The fifth graders did a great job on their koi fish. We drew them together, but the students were allowed to change things such as eyes and fins. The students then learned how to shade with oil pastels. They could do their fish any color they wanted, but had to use three values in the scales for the shading. When they were done with coloring the fish I explained that they needed to mix together at least two colors in the background, using wet-in-wet. We discussed the importance of contrast when choosing a background color.
