Linear Functions ReviewLinear Functions Review
Rules of the game. Each person in your group needs to answer. Answer Sheets will be collected at the end of the period. Answers will be entered on the calculator. Some are fill in the blank while others are multiple choice. The first person in with the correct answer gets the points for
his/her group. You have until the music stops playing to answer the
question. However, some questions will require more time and will be given when appropriate.
In the event of a tie the points will be split among the groups.
