Why do we use symbols? When drawing a map to scale, it is important to include as much detail as possible. However, not all the detail will fit on the map, so we use different images, abbreviations and letters to represent the main items on the map. Activity Draw a map that shows your route to school but do not use any words! 4 of 31 © Boardworks Ltd 2006

What can we learn from place names? The endings of many place names tell us about their history… Can you spot any place names like these on the map? 14 of 31 ending of place name meaning barrow hill barton/worth farm bury (or burgh) fortified place caster/chester/cester Roman city den/dene/deane wooded valley garth enclosed field gate street or road grange grain store ham village ley meadow stoke holy place wick dairy © Boardworks Ltd 2006

Describing places The village of Thakeham lies to the east of Pulborough. It has a church and is joined to the village of Abingworth by a secondary road. The name of Abingworth suggests that this place grew up around a farm. To the south-west of Abingworth is the site of an old Roman Road. South of this road are tumuli - burial places of the Ancient Britons. 15 of 31 © Boardworks Ltd 2006

Grid references Geographers use maps constantly but sometimes they can seem a little confusing. Maps are often covered by a grid. 32 31 This is so we can find places more easily. These grids have numbers. 30 29 28 27 26 25 24 23 01 02 18 of 31 03 04 05 06 07 08 09 10 11 © Boardworks Ltd 2006

Eastings and northings Specific areas on maps can be identified using a grid reference. These come in the form of numbers, for example 0431. To find this place on a map is simple: The second two digit number is called the northing. This is the number at the side of the map. 32 31 30 29 28 The first two digit number is 27 called the easting, this is 26 25 the number along the 24 top or bottom of the map. 23 19 of 31 01 02 03 04 05 06 07 08 09 10 11 © Boardworks Ltd 2006

Finding a grid reference To find the number 0431, first place your finger on the 04 line. Place a second finger on the 31 line. Draw your fingers together along the lines. 32 31 30 29 28 27 26 25 24 23 20 of 31 01 02 03 04 05 06 07 08 09 10 11 The square you are looking for is to the north-east of where the lines cross. © Boardworks Ltd 2006

Six figure grid references Sometimes geographers need to be more specific and will use six-figure references, such as 045315. 32 31 30 Don’t panic. Click on square 045315. 29 28 27 26 25 24 23 01 02 24 of 31 03 04 05 06 07 08 09 10 11 © Boardworks Ltd 2006

Finding a grid reference You can then imagine that you can divide box 0431, further into a ten by ten grid. Use the same rules for finding eastings and northings. 32 9 8 7 6 5 4 045315 will be here. 3 2 1 31 04 25 of 31 1 2 3 4 5 6 7 8 9 05 © Boardworks Ltd 2006
