Lesson details

Key learning points

  1. The whole has been divided into __ equal parts.
  2. Each equal part is one-__ of the whole.
  3. Fractions can be represented as part of a shape or a set.

Common misconception

Children will often think that the total number within a set is always the denominator as shown in the plates and cupcakes example on the slides.

Put a set of 12 counters (or any countable objects) onto a mini-whiteboard. Children should practise dividing the set into equal groups, drawing rings around them. Repeat, 'The set has been divided into _ equal groups so the denominator is _'.

Keywords

  • Part - The whole is all of a group or number.

  • Whole - A part is a section of the whole.

  • Equal - Have the same quantity or value.
