• Which of these features should a map include?

  • title
  • scale
  • north arrow
  • key
• Maps are divided into a series of squares known as a grid. These grids help us to locate features on the map
• Maps include a scale to help us work out distance between points on a map
• • Scale is usually written on a map as a ratio. For example 1:25000. Scale can also be shown using a scale bar.
• A grid reference is a useful tool for identifying any square on a map. This is done by reading the numbers from the eastings and northings. This gives you the grid reference of the square.
• True or false? When looking for a grid reference, always go 'up the stairs' before going 'along the corridor'. False. Always go 'along the corridor' then 'up the stairs'. This means always read the number from the eastings before the northings.
• What are grid references?

  Coordinates on a map.
• What are eastings? 


  Eastings are vertical lines that you can follow from the left of the map to the right.
• True or false? When calculating grid references, you should use the northings first. 


  False
• True or false? A six-figure grid reference is more accurate than a four-figure grid reference


  True
• Which method helps to calculate a six-figure grid reference?

  Dividing each grid square into 100 smaller squares can
• Why do maps have scales?

  It would be impossible to draw a life-size map and we need to know the scale to work out distances.
• Why can't you always use a ruler to measure distance?

  The distance you need to measure will not always be a straight line.
• If the scale of the map is 1:25000m, how far would 4cm on the map be in real life

  In the real location, 4cm on the map would be equal to 100,000cm, which is 1,000m or 1km. This is because 1cm on the scale is equal to 25,000cm in real life
• what is A scale bar?

  A scale bar is a line or bar divided into parts. It is used to show what distances on the ground look like on the map.
• True or false? It is easier to measure the length of curved lines, rather than straight lines, on a map.


  False
• How can the length of curved lines on a map be measured? 

  Using a strip of paper
