Math Monday: Overlapping Shapes

Perspective

M: "Try drawing a rock in front of a ball." 
(Miss O starts with a giant rock)
O: "A rock in front of a ball?
Oh.
Then there. 
(omits drawing a ball at all).
Or I can draw a bigger ball."

This exercise in photos, does not seem like an exciting activity, but as the conversation illustrates, a lot of perspective-taking was going on!
Math and art often go hand-in-hand, so we don't shy away from exercises that include both.
