  2. Mapwork skills Grid references

  3. Grid References • Grid= square • References= numbers • It can be in: • four-figure (4532) or • six-figure(452327)

  4. The Golden Rule!!! ‘Go along the corridor, then up the stairs’ or the Lsign! Back to Front!!

  5. The four-figure grid reference for this square is 7725 26 25 77 78

  6. In order to give something a six-figure grid reference, imagine the larger square split into one hundred smaller squares. 26 25 77 78

  7. Then add numbers 1 to 10 between the main lines. 26 9 8 7 6 5 4 3 2 1 25 1 2 3 4 5 6 7 8 9 77 78

  8. To work out the six-figure grid reference, first go along the bottom line and calculate the first three figures. 26 9 8 7 6 5 4 3 2 1 25 1 2 3 4 5 6 7 8 9 77 78

  9. The church’s first three figures are ...... 773 26 9 8 7 6 5 4 3 2 1 25 1 2 3 4 5 6 7 8 9 77 78 773

  10. Next, work out the last three figures by going up the side of the square. 26 9 8 7 6 5 4 3 2 1 25 1 2 3 4 5 6 7 8 9 77 78 773

  11. The last three figures are ...... 253 26 9 8 7 6 5 4 253 3 2 1 25 1 2 3 4 5 6 7 8 9 77 78 773

  12. So, the six-figure grid reference for the church is ..... 773253 26 9 8 7 6 5 4 253 3 2 1 25 1 2 3 4 5 6 7 8 9 77 78 773

  13. What is the six-figure grid reference for the bus station? 26 9 258 8 7 6 777258 5 4 3 2 1 25 1 2 3 4 5 6 7 8 9 77 78 777

  14. What is the six-figure grid reference for the picnic area? 26 9 8 7 6 5 4 3 2 1 25 1 2 3 4 5 6 7 8 9 77 78

  15. There are no lines in the squares on a real OS map! You have to estimate. What is the grid reference for parking? 26 P 25 77 78

  16. What is the grid reference for parking? 26 774257 P 25 77 78
