Lesson details

Key learning points

  1. The language 'for every' can be used to describe the relationship between the distance on the map and on the ground.
  2. A double number line can represent the relationship between the distances.
  3. The representation helps to identify the calculations needed to solve the problem.

Common misconception

Scaling values can be done using addition and subtraction.

The ratio relationship between the values when they are scaled must remain the same.

Keywords

  • Scale - A scale is used to show how the distances on a map or plan relate to distances in real life

  • Scaling - Scaling is the operation of changing one value to another using multiplication or division, using the same factor or divisor

  • Double number line - A double number line is used to show the relationship between two values, in this case, the distances on the plan and those in real life

Model that the relationship between the plan and real life distances is the same for all values so if a measurement on the map or plan is doubled then the real life distance is also doubled.
