Mandalas: Concentric Circles

I talk about concentric circles with my 2nd grade students every fall.  We talk about how concentric circles are many circles with the same center, and I show them images of mandalas from all over the world.  I also tell them that they are sacred and tell the story of a special place of the artist. 
Next, they start designing their own mandala, using ice cream lids as the outer circle, and other round containers to make more circles.  Students also pick up quickly that all of the mandalas are cymmetrical (the same on both sides.)  They also use templates and other objects in the Art room to add geometric shapes (the ones with names: circle, square, triangle, etc.)
Here are some amazing artists:
