Lesson details

Key learning points

  1. To divide an object, shape, set of objects or quantity into quarters, you need to divide it into 4 equal parts.
  2. If you have 3 of those parts, you have three-quarters.
  3. It can be helpful to use a bar model to help you find three-quarters of a number.

Keywords

  • One-quarter - 1 of 4 equal parts of a whole.

  • Three-quarters - 3 of 4 equal parts of a whole.

Common misconception

Children may find one-quarter rather than three-quarters of an amount.

Use gesture, colour and/or circling to highlight three-quarters of an amount. Use the stem sentences, 'one-quarter of the whole is ___, two-quarters of the whole is ___, three quarters of the whole is ___'

Ensure children have opportunities to explore this concept practically using concrete resources throughout this lesson. Continually acknowledge that the whole has been split into 4 equal parts and that this time, we want 3 of those equal parts.
