- There is a square on the right side of the first and third hangers.
- The third hanger has all the shapes from the first two hangers.

What do you wonder?
Your answer may vary, but here are some samples.
What do you wonder? Possible responses:
- Is the circle the lightest shape?
- Which shape weighs the most?
- Why does the last hanger have many more shapes than the other two hangers?
- Why is the last hanger still balanced if it has shapes added to each side?
