This is a 2-Day Lesson. This would take place towards the end of a unit involving the Pythagorean Theorem.
Arrange students in groups (8 groups, about 3 students per group).
There are 8 challenging problems that all involve the Pythagorean Theorem, as well as other previous knowledge.
Give the students 1 class period to work with their groups on all 8 problems. Alert the students early on that each group will present one problem on the board tomorrow. (Group #1 will present problem 1, Group #2 will present problem 2, and so on.) All problems and images can easily be copied and pasted on a SmartNotebook presentation.
During Day 1, the teacher can supervise groups, and make sure that each group is comfortable with the problem that they are supposed to present to the class the next day.
Check to make sure each student completed all problems. Each group presents the solution to their problem. The teacher checked that each group understood their corresponding problem, so the presentations should run relatively smoothly. Also attach a grade to the presentation if you want.
