Use 4-figure and 6-figure grid references to locate places on a map

Apply the 4-figure grid-reference convention (letter + number, e.g., D5) to locate places on the MG-11 grid chart and the MG-5 town map. Extend to 6-figure grid references for stretch students. Use the 'read across first, then up' mnemonic. Complete the school-yard treasure-hunt routine.

Successors
Common misconceptions
  • Reading the grid in the wrong order (read ACROSS first - letter or first digits - then UP)
  • Confusing rows and columns (letters are columns; numbers are rows in the standard convention)
  • Treating grid references as exact-points rather than as squares (a grid reference names a SQUARE on the map)
