I realized that my kinder students were having trouble drawing circles and ovals that were distinguishable from each other and that my first graders drew them so fast they couldn't tell the difference either.
We did these gumball machines to try to drive in the difference between the two shapes.
The frames had a circle-oval border.
The gumball machines were supposed to have all circle gumballs inside.
As simple a project it was the kids really enjoyed making these!
