Learn about the math behind patterns and create all sorts of unique combinations and variables using these math and art integration lesson plans. Working in groups of up to 3, students place a sheet of paper between the base board and the top plate. Students choose one of the 3 gears and place inside the top plate. Using a pencil, student rotate the gear around the top plate to reveal a shape. Younger students will learn about the relationship and recognize patterns between the top plate and size of gears.
