All kids seem to love Tropical Fish. I have done this lesson in both 1st and 2nd grade. First, we drew fish. Then we decorated our fish with lots of designs. These designs were outlined in oil pastel. Then the fish were painted with watercolor. The entire fish was cut out and glued onto blue paper.
For students who were done early , I let them add sea weed, fish, treasure chests, or anything else that can be found in the ocean.
