Geocaching no longer requires expensive equipment, making it much more accessible to beginners. For students, an expensive and elaborate GPS device isn’t necessary. GPS enabled smartphones offer the most economic option for geocaching, as many students already own the equipment, and need only purchase a geocaching app to participate.

For younger students, or those without smartphones, look for a device that is user friendly for inputting waypoints, accessible—and most importantly—durable. Expect to pay around sixty dollars per unit. I use the Garmin eTrex 10 Worldwide Handheld GPS Navigator with my students—though it is a bit more expensive than the Geomate Jr. Geocaching GPS.

Most geocaching is done in groups, so regardless of the device used, a successful geocaching lesson only requires a few devices. I have seven devices, which works out beautifully with a class of 25-30 students. For financial support, don’t forget to use the school’s PTO/PTA grants, fund raisers and Donors Choose (of course, purchasing a device will be a tax write-off!).

Here are a few of the smartphone apps I use with my students:

Geocaching ($9.99). The official geocaching app from Geocaching.com (the Mothership of geochaching), this is the most expensive app on the market as well as the highest quality. Users will get access to the locations of registered caches and clues, and the app even offers the ability to submit your finds. This app is very easy to use and perfect for beginners and pros.

Geocaching Intro (Free). This is the free version of the GroundSpeak geocaching app, the company that runs the Geocaching.com website. This is the app that I recommend to my students. While limited, this app reveals three geocaches near your current location per day; provides the necessary coordinates, hints, and descriptions; and delivers the directions to the hidden cache. I love the vibrating-chirping alert that warns you when you’re getting close to the cache site—a feature not included on the more expensive sister geocaching app.

Once equipped with devices, it’s time to engage the students in a meaningful lesson that will challenge their map-reading skills while affording them opportunities to work collaboratively and solve a problem.

There are several activities I have done with my students, from upper elementary to high school. To start, all students were taught how the device worked and learned how to input data as well as retrieve and set their own waypoints. Our fifth grade students became such experts that the principal asked them to lead the staff in professional development. From there, our principal hid staff handbooks all around the campus and had the teachers use the coordinates (and help of their fifth-grade buddies) to locate their handbook.

Activities can range from solving riddles to searching for hidden rubber ducks to embarking on geometry scavenger hunts. For a beginner lesson, hide caches near a specific tree, bush, or flower. Once students have located the cache, have them take a picture and identify the species of flora. (Placing a leaf from the tree or plant in the container would also work). You could also place a toy animal, picture, tooth, claw or hair sample inside the cache container and have students identify the object. Once all caches have been found, have them create a photo/identification booklet.

If you want students to develop curiosity about geography, math, science, and the world around them, then give geocaching a try. It’s a great activity for ESL and special needs students, allowing them the opportunity to work collaboratively and solve problems while incorporating the characteristics of an active and engaged learning environment.
