Here are some student examples:
These two pictures have already appeared on my blog because they have both been displayed at art shows for Youth Art Month:
Before the students began their birds, they completed the pointillism worksheet I created. This worksheet helps the students understand the concept of mixing colors with dots. As they work, I allow them to periodically place their worksheet on the blackboard with a magnet so they can look at it from far away. Before they begin the worksheet, I give them lots of ideas for mixing the colors. For example, tan can be included in yellow-orange; to make purple, the students may want to use pink or raspberry instead of red so it won't be so dark.
