2nd Grade - Rainbow Stencil

I've been experimenting with fun ways to incorporate color mixing in my classroom since the beginning, and this project has sort of stuck.  It's a two or three parter, where we first make a stencil or a shape or drawing and then trace it onto a strip of paper six times.  Then we use only the primary colors to get a rainbow into each shape.  It's simple and pretty direct, but a good painting project to close the year out for the second grade.
