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.
