Use the Earth's magnetic field to easily navigate the "Compass Challenge." Help your students practice key measurement skills as they play this exciting game. Students first read the compass to determine the direction of travel for each step, and then travel a predetermined distance using the course cards provided. Each team is provided a course card with a starting point from one of the survey tags. Grading is a snap because each course ends at a different point. The course can be set up in any size area, from at least 6 m2 to as large as 20 m2. Kit includes enough rope for 20 m2, orange survey tags with twist ties, cup-markers, course cards for 34 different courses, and complete instructions with answer key.Super Value Kit is complete for 20 student groups. All materials are reusable! Compasses are required and available separately.
