Texas Instruments: Numb3 Rs: The Four Bugs Problem: Step on No Pets

Based off of the hit television show NUMB3RS, this simulation has students model the Four-Bug Problem in order to see the general concept of pursuit curves. Each student takes on the role of a bug, and are placed at each corner of a large square. Students then act out moving towards the "bug" to their right, dropping pennies as they go. When students are finished, they can explore their curves, the lengths of curves, etc. The lesson also comes with a very comprehensive Geometer's Sketchpad file.
