Math

The following are math-related GPS or geocaching activities:


 * //Perimeter:// Use the Trip Computer on the GPS to calculate the perimeter of an area on campus such as the basketball court, playground, or outside of a building.


 * //Sorting:// Collect a variety of small objects (erasers, coins, counters, buttons, etc.) and place them in various caches. Once students find the caches, they return to the classroom to examine and discuss the content of the caches, determining different ways to sort the items inside. Older students can use a graphing program to create a graph representing the items inside the cache based on the category in which they decided to sort the items. Create a Graph is a free web-based graphic tool.


 * //Rivers with Excel:// Place packets of word cards with different rivers from around the world in caches. In each cache place a packet of index cards. You can choose to make each cache based on one continent or you can mix up the cards. Students then uses Excel to create a table of their data as well as a bar graph.


 * //Money:// Scan or find photos of currency from around the world. Place the currency in caches. Once students find the caches, they return to the classroom to identify the currencies and find the exchange rate for each currency in US dollars using an online [|currency converter].
