2. Every Person in your group needs a sheet of paper, a pencil, and a calculator.
Every Person in your group needs a letter, either T, R, A, S, or H. Put that letter and your color at the top of your paper (both sides).
Every Person will solve the problem on their own paper(you may get help from the members in your group).
Only the person whose letter I call will come up and show me their paper.
You get one point for a correct answer.
If correct, you can shoot for bonus points. 2 from the two point line or 3 from the three point line.
