        Harry Makes a Big Splash with Positive and Negative Numbers

        In this Cyberchase video, Harry, his friend, and his cousin Harley form a swim relay team. They get timed in three different strokes to see who should swim which one in a relay. They look at the results and try to find the combination of times which will yield the lowest overall relay time. In the accompanying classroom activity, students pair up and play a game that gives them practice adding positive and negative numbers on a number line.
