GPS Master

“GPS Down!” is an interactive mapping game where students plan road-trip routes between assigned U.S. cities without GPS, choosing contiguous interstates and directions. Using a draggable, rotatable map scale, they estimate total mileage, then compute time (at 60 mph), fuel use (25 mpg), cost ($3.50/gal), and fuel stops (400-mile range). The app grades route accuracy and estimates, giving a report card and side-by-side comparison to the actual values to reinforce map reading, measurement, and real-world math.
