This document provides instructions for a class activity where students will work in groups to collect four envelopes, each containing part of an equation to model a skier's path. To collect the envelopes, the group must complete a math problem, win a game of rock paper scissors, spell a word backwards, and find one envelope hidden in the classroom. Once collected, the group can open the envelopes and work together to fill out a worksheet modeling the skier's path and be the first to graph the function on a calculator.

1. Class activityUnit 8.5

2. Materials:Per group:One graphing calculator (provided)One “path of a skier sheet” (provided)Writing utensil

3. InstructionsYou will be divided into the groups of your wiki (8.1, 8.2 etc.) As a group, your job is to collect four envelopes, each envelope containing a part of an equation to model the path of a skier (e.g. one envelope is speed, another is height of the hill)DO NOT OPEN THE ENVELOPES AT THIS POINT

4. To collect your envelopes you’ll need the following clues:One of the envelopes is hidden IN THIS ROOM...muahahahahYou will need to complete a math problemYou will need to win a game of rock paper scissors (best two out of three!)You will need to know how to spell backwards!

5. Once your group has collected their envelopes, each group can start working on their page “path of a skier”, by opening their envelopesThe group to complete the sheet first, and graph their function using a graphing calculator wins!Good luck!
