Happy Thanksgiving everybody!
Note: We split this week's work into problems for students that needed work on Pythagorean Theorem and more advanced problems for older students, so the group that you were in did not get all the problem sets mentioned below (and don't worry about it). Just do and check the problem sets you did get.
