# Prepare a Presentation

Explain how you revised your work, and why you felt the revisions were necessary. Give examples of the types of mistakes you made.

# Challenge Problem

- Play the same type of game by drawing a figure on a sheet of paper, but do not show the figure to your partner.
- This time your partner needs to determine what shape you drew by asking yes-or-no questions but can’t be about the number of sides—the questions must be about the diagonals, the angles, or other features of the figure. Your partner should not try to guess the shape until sure that the answer is the only shape possible.
- Once your partner guesses the figure, switch roles.
