The purpose of this activity is to engage students in finding locations from descriptions given and using these to solve a problem.
The background knowledge and skills that need to be established before and/or during this activity are outlined in the diagram below:
- Finding a location using a grid reference
Set up a patrol boat, for a game of battleships, sitting on B3 and B4.
- The compass
Draw an arrow showing the direction NE (Northeast).
- Using East-North grid references on a map
Find 1260 kmE, 4796 kmN, on the map provided.
- Measuring angles
Use a protractor to measure an angle.
- Solving a problem involving angles and grid references
If a boat sails from 1220 kmE, 4840 kmN to 1230 kmE, 4842 kmN, find the bearing (angle of journey clockwise from due North) the boat followed.
To solve this problem, the students may locate the positions given with a combination of calculations and measurements. The guidance given should be chosen in sympathy with their skills and preferred method of solution.
The procedural approach (show more)
- The student is able to solve the problem, with guidance.
Prompts from the teacher could be:
- Mark, on the map, the intended route.
- Find the grid reference for where the pilot wanted to land, on the map.
- Mark, on the map, the route the plane took.
- Use a protractor to measure the angle of deviation from the original flight.
The conceptual approach (show more)
- The student is able to solve the problem independently, within the context given.
