The actual art-making part of this activity was very simple: Trace some shapes onto white paper (I had brought my collection of cardboard and plastic shapes with me) and then color in the resulting spaces.
I introduced the words overlap and intersect and modeled tracing a few shapes to demonstrate the meanings of the words. I made sure students understood that each shape needed to overlap at least one other shape, so that all the lines would intersect. I then explained that each resulting shape/section would need to be filled with a pattern, and that no pattern could be repeated. And just to throw in another math concept, I asked them to trace an odd number of shapes, more than two and less than ten. They traced the shapes with a pencil first, then colored the spaces in, and then went back and outlined each original shape with a black crayon.
This was an easy, easy lesson that needed no prep at all. It would be great for a substitute (well, I was substituting!). I happened to have shapes with me, but I would bet that in most primary classrooms one would be able to find some shapes to trace. If not, students could make their own, with each student making one shape and then all students at that table sharing each others'. And there's no rule that says they have to use geometric shapes, but I do think the resulting shapes from overlapping are very interesting and it would be a great math extension to have them name all the resulting shapes, or some additional art concepts could be included by having students use all warm or all cool colors, or some other defined color combination.
