Complementary Color Wheels

In 7th grade we are reviewing the color wheel.  Students first worked on a color wheel worksheet filling in each piece using colored pencils.  They chose 8 colors they wanted for their final drawing and began their complementary color wheel which is shown below.  Instead of just creating a plain colored background, students practiced shading with colored pencils.  The objects were later colored in the complementary color inside the triangle (make sense?)  Just for review here is a link to a color wheel (scroll down the page a bit)-the complement is directly parallel.
