###### ​Overview

In FR Quad students solve four free response questions and compete against other teams to score points for the answers they write up on the class grid. Students will review important concepts about average and instantaneous rates of change and the rates of change of linear and quadratic functions. Get ready for a lively and fast-paced review activity that encourages student-to-student conversations and high-level collaborative work!

# Lesson Handout

###### Instructions

Prep: Make copies of the four free response questions. You will need one copy of each FRQ per group, not per student. Choose two squares to be the “magic squares” (instructions below).

Play:

1. Create groups of 3-4 students. Give each group a different colored whiteboard marker. Project the game board provided on page 2 of the activity handout.

2. Teams work to complete the FRQs in whatever order they wish. Once they have an answer, they write it in the proper box on the screen using their team’s colored marker. If another group believes the answer is wrong, they can write their own answer beneath it.

3. Once a team has written in a particular square, they cannot write in that square again, even if they want to modify their answer.

4. Only one person from each group can be at the board at a time. All other group members must stay at their table.

5. Special points are given for completing a full FRQ, correcting someone else’s answer, answering a part (e) question, having 4 in a row, or having answered a question in a Magic Square. See point values on page 3 of the activity handout.

6. Once all the questions are completed or there are only 5 minutes remaining in class (whichever comes first), reveal the correct answer to each square and identify which team won the square. Emphasize to students the importance of proper justifications, especially in FRQ #2. Providing rationale for selecting a function type to model a scenario is a critical skill in AP Precalculus and we want students to practice giving these justifications early and often.

7. Have students calculate their totals and award a prize for the first-place team.
