3rd graders really impressed me with these. They listened to directions and also got creative. I asked them to include the table top and background, a vase, and flowers which had to include at least one sunflower. We decided it would be cool to sign our vases like Van Gogh did in his paintings. I have started using liquid watercolors and really like the results. The only problem I've had is if a student forgets to rinse their brush and dips into another color, but that's only happened a few times. I've found the pan watercolors have gotten cheaper- are gooey and don't last very long.
