Geocaching involves hiding and seeking treasures using GPS coordinates as clues. It can be integrated across curriculums to teach map skills, science, and literature. Teachers can hide caches on school grounds to teach longitude and latitude or have students find multiple caches and plot coordinates on a map for map skills practice. Geocaching utilizes GPS and maps to engage students in an outdoor scavenger hunt.
