Finding Caches Using Math
Teachers are currently using geocaching as a way of teaching math, especially algebra. Teachers give students math equations to come up with longitude and latitude degrees, including the tenths, hundredths and thousandths of minute information.
Students then use this information to find the GPS coordinates of a hidden cache either in the woods or near their school. The goal of these lessons is to provide a fun way of learning algebra. Students are more likely to learn a difficult subject like this if they are exposed to it in a fun environment.
This also teaches teamwork since students must usually work together in groups. Generally, a group of students is given a GPS unit. Once they figure out the longitude and latitude, they can punch this information into the GPS unit to find the cache.
Just like regular geocaching, however, the unit will only get students so close to the cache. From there, they must do a little bit of treasure hunting on their own, searching around the area. Finally, they may have to do a little digging or simply searching in the bushes. If you are dealing with especially young children, teachers may want to leave the caches visible.
For students, the cache rewards are usually pretty simple, i.e. stuff they can use in the classroom (pencils, crayons or notepads) or fun toys.
