Based on Dr. Seuss' One Fish, Two Fish book I really like this lesson plan. It was the first time I've used "Tracers". Oh my! Gasp! I know how some of you feel about using tracers, but I had these oval foam shapes from Arts and Scraps and thought they would be a great starting poing for our fish. Maybe it was my imagination but the student stress level was zero. They LOVED using the foam and spent more time and attention to the fish and their expressions.
