Four-figure grid references Lets have a look at a couple of other examples. You work out the answer before it appears! First, a RED SQUARE 39 The EASTING is: 22 The NORTHING is: 36 38 37 The four-figure grid reference is: 36 2236 35 21 22 23 24 25 26 Click for next slide… Click me

Four-figure grid references Final chance to practice…. . This time, a BLUE SQUARE 39 The EASTING is: 24 The NORTHING is: 35 38 37 The four-figure grid reference is: 36 2435 35 21 22 23 Hope you got it right. Time now for a little test. 24 25 26 Click for next slide… Click me
