- 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
“If your child 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?”
