Once everyone finishes their explorations, you all will receive a number. Get into groups according to the number you've been given.

In the number groups, there will be at least one representative from each letter group. Take turns teaching one another what you have just learned. You may use the computer, paper and pencil, straight edge, compass or any other materials.

When everyone is finished teaching, we will summarize as a class. Have questios, comments, conjectures ready!
