Halves and QuartersYear 2 Lesson Plan

National Curriculum: Mathematics — Number: fractions — recognise, find, name and write fractions ½, ¼, 2/4, ¾ of a length, shape, set of objects or quantity — Year 2

Overview

Pupils develop their understanding of halves and quarters as equal parts of a shape or a set of objects. They learn that fractions must be equal parts, find halves and quarters of shapes and quantities, and begin to relate these to simple equivalence (two quarters = one half).

Learning Objectives

  • Recognise that a half is one of two equal parts and a quarter is one of four equal parts.
  • Find halves and quarters of shapes by dividing into equal parts.
  • Find half and a quarter of a set of objects.
  • Recognise that two quarters are equivalent to one half.

Key Vocabulary

half
One of two equal parts of a whole, written as ½.
quarter
One of four equal parts of a whole, written as ¼.
equal parts
Parts that are exactly the same size.
whole
A complete, undivided amount.
equivalent
Equal in value — ½ = 2/4.

Suggested Lesson Structure

10m
Starter

Fold a paper rectangle in half. Ask: are both parts the same size? Fold into quarters. Are all four parts equal? Establish: fractions must be equal parts — an unequal cut is not a half.

20m
Teaching input

Introduce ½ and ¼ notation. Model finding half of a shape (fold and shade), half of a group (share 8 into 2 equal groups = 4 each). Extend to quarters. Show equivalence: fold the half in half again to show 2/4 = 1/2 on the same paper.

15m
Guided practice

Pupils shade half and quarter of given shapes, then find half and a quarter of sets of objects (e.g. 12 counters). Record using fraction notation.

10m
Independent practice

Pupils complete a halves and quarters activity: identify whether shapes are correctly halved, find half and quarter of amounts up to 20, and explain why 2/4 = 1/2 using a diagram.

5m
Plenary

Show a shape divided unequally and labelled 'half'. Ask: is this correct? Pupils explain using the language of equal parts.

Common Misconceptions

  • Pupils accept unequal cuts as halves because the piece 'looks about right' — stress equal parts rigorously.
  • Thinking that ¼ must always look like a square quarter of a circle — show quarters of different shapes.

Prior Knowledge

Pupils should already be able to:

  • Ability to share objects equally between 2 or 4.
  • Experience with halving from informal activities.
