My youngest students always find our color mixing unit so magical. My favorite book to introduce the concept is Mouse Paint by Ellen Stoll Walsh. They love guessing what colors the mice will mix up next and I find many of my students I had previously in PreK will actually remember the formula for creating new colors! They are amazed that you can create so many new colors out of the three primaries.
After talking about the primary colors, I showed them a Powerpoint of Mondrian paintings, where we noticed that he used lots of rectangles and squares as well as the primary colors. They made a collage with black paper strips, creating different sized rectangles and squares.
The next class we went over the color mixing formulas. I worked with the students in small groups, making sure to only keep two primary colors at each table. So, I had an orange table, a green table, and a purple table. This really helped to give them the full color mixing experience rather than ending up with brown paint all over their papers. They mixed the colors inside each square or rectangle. They all had such a blast and were thrilled to discover they really could make a new color just by mixing two primary colors. Success!
