I think that making color wheels arevery important. They can be used as a very helpful took for students to use throughout the semester as they are playing with color. It also helps with the visual learners to be able to SEE how colors changewhen they are placed next to each other.
For this color wheel students will make their color wheel using old magazines and markers. Their color wheel will have two wheels, whichwill be secured but a pin in the middle. This will allow the wheel to spin. After students make the color wheel and there are many (many, many) discussions about how primary colors make secondary colors, and what complimentary colorsare, students will use their color wheels to help them mix colors and create a painting of their own.
