"Rolling" Into Trigonometry

Spirit Week 2003

In the "Spirit" of things, what better math activity for Pajama Day than using coffee cans to collect data as part of an introduction to trigonometric functions?  Students in Accelerated Algebra 2 (top left, bottom right, and bottom left photos) and Math 3 (top right and bottom center), suitably attired in sleepwear and assisted by various stuffed friends, complete an exploration into periodic behavior and radian measure.
