Instructional Ideas

• Use a map of your local area that does not have any coordinates on it

Classroom Considerations

• Create groups so that everyone actively participates in the decision making
• Print maps large enough so all can see the details
• The third part in a nine-part series

Pros

• The background information provides a history of coordinate systems used
• Provides assessments to use before, during, and after the activity

Cons

• 8.F.A.1 might not be the best math alignment available
