Scale and similar shapes (age 11+)

Mathematics · Ratio & Proportion · procedural

Use scale factors to interpret and create scale diagrams and maps, calculating real-life distances from map measurements and vice versa

What mastery looks like

  • Calculate a real-life distance from a map measurement using a given scale (e.g. 1:25,000)
  • Draw a scale diagram of a room using a chosen scale factor
  • Convert between map distance and actual distance in problems involving different units

Check your understanding

If Scale and similar shapes (age 11+) looks at a map where 1 cm = 50 km, can they work out the real distance between two cities that are 4.5 cm apart on the map?
