This is a great activity to teach elementary students about using a compass. This can be incorporated into a science unit on magnetism or a social studies unit on maps.
This document gives you the idea of the lesson. It takes about 20 minutes to prepare your orienteering (compass) course. You can use this as a one-lesson or two-lesson activity. Extensions are included. I have typed this document with a compass course for my school's campus, so please take your time to edit it to your school's campus.
This is a challenging but fun activity!!!
