Cyberchase: Solving the Riddle
Math → Geometry → Measuring Angles
Jackie, Matt, and Inez work together to solve a pirate's riddle. When they find the boulder shaped like a hen, Inez points out that the riddle contains more information: they need to record the angle at which the boulder was found from Jackie's position. Using yoyo string, paper, and pencil, they draw the angle so that they can remember it.
