1. Challenge • Any volunteers? • Can the rest of the people direct him/her to his/her wallet without touching him/her? • Are there any other ways to give him/her directions to where he/she needs to go?

2. Mathematics 8-point compass Primary Four Miss Grace Ong Miss Wang Ai Pei

3. Lesson • Introduce 4 basic directions. Use the mnemonic ‘Naughty Elephants Spray Water’. • Introduce NE, NW, SE, SW. • Practise these 8 directions in class.

4. Emergency Mission: Your country is under attack. Your enemy has planted a nuclear bomb and you have to retrieve a code to stop the bomb from detonating.

5. 3. Your enemy has left his mark behind with this symbol ( ). Use the instruction sheet and map to find the symbol. Instructions • Work in groups of 4 – 5 pupils. 2. Each group will be issued a map of the school, an instruction sheet and a marker. 4. There is a letter beside each symbol. Write all the letters to form a code.

6. Reminders • Point out where north is. • Give pupils an estimated time to finish task. • Tell pupils not to run for safety • reasons. • Expected behaviour. • Confined area.

7. Understanding B C D E F A H G I J

8. Reflection Think about the process… OFF YOU GO!!

9. Bringing it back - Resources to prepare on your own • Map • Instruction sheets • Symbol cards • “Codes” - Answers • Water-soluble markers • PowerPoint Slides for the lesson

10. Bringing it back – Planning • 1. Get a school map • Simplify the map such that only items/locations that the kids need are on it. (Can be done as you do the next step.) • Indicate North on the map. (Need not be the real north.)

11. Bringing it back – Planning • 2. Identify a starting point • Find a starting point that will be easy for kids to start off such as an open space. • From the starting point, look for obvious spots for clues . (Use spots that you can easily plan the routes.)

12. Bringing it back – Planning • Planning of routes • Plan different routes leading to the same locations. •  To avoid everyone running in the same directions. •  To prevent herd syndrome

13. Bringing it back – Planning • 4. Form clues • Give only easily solved clues • Confine locations to a manageable area for safety reasons and keeping the task to a reasonable lesson time.

14. Bringing it back – Planning • Come up with all the possible answers • Laminate all the clue cards and letters (to re-use in future).

15. Bringing it back – Execution • Put up the laminated symbols only on the day itself before the lesson. • Conduct a pre-activity briefing informing pupils of the task, rules of the game and safety rules. • Do a demo practice in class to give the class an idea of what to expect.
