Reading measuring instrument scales and estimating everyday measures

MA24-10

This lesson is coming soon.

In this lesson

Read a value from an analogue or digital measuring scale between its marked graduations, and make sensible real-world estimates of everyday lengths, masses and capacities.

What it covers

  • Reading the value of an unlabelled graduation on an analogue scale (e.g. a ruler, jug, dial, thermometer) by first working out what each small interval is worth
  • Reading values directly from a digital display
  • Making a sensible real-world estimate of an everyday length, mass or capacity (e.g. the height of a door, the mass of an apple) using known reference objects, without measuring

For teachers

This GCSE Maths lesson teaches reading measuring instrument scales and estimating everyday measures. By the end, students should be able to read a value from an analogue or digital measuring scale between its marked graduations, and make sensible real-world estimates of everyday lengths, masses and capacities. It works through two worked examples and the mistakes examiners report.
