🍕 Halves, Quarters and Fair Shares

Class 3 Maths · Unit 6 of 12 · about 100 minutes

Introduces fractions through fair sharing: halves, quarters and three-quarters of a whole shape, then of a small collection. Children learn that equal parts are required, read and write ½ and ¼, and find half or a quarter of a group of objects. Formal fraction notation beyond quarters is left for Grade 4.

What your child will learn

  • Students will be able to identify and make a half of a shape, checking that the two parts are equal, and write it as ½.
  • Students will be able to identify and make quarters and three-quarters of a shape and write ¼ and ¾.
  • Students will be able to find half and a quarter of a small collection of objects by sharing equally.
  • Students will be able to compare half and quarter of the same whole and explain which is bigger.

Lessons in this unit

  1. Halves: Cut or fold a whole into two equal parts, name each part a half, write ½, and check that unequal parts are not halves. Shapes only.
  2. Quarters and three-quarters: Fold a whole into four equal parts, name one part a quarter (¼) and three parts three-quarters (¾), and see that a quarter is half of a half. Shapes only.
  3. Half and quarter of a group: Find half of a collection by sharing into 2 equal groups and a quarter by sharing into 4 equal groups, using counts that divide exactly (even numbers up to 20 for halves; 4, 8, 12, 16, 20 for quarters).
  4. Which is bigger: half or quarter?: Compare half and quarter of the same whole using pictures, explain that more equal parts means smaller parts, and use the idea in fair-share stories.

Key words

whole
The full thing before it is cut or shared.
half / halves
One of 2 equal parts. Two halves make a whole.
quarter / one-fourth
One of 4 equal parts. Four quarters make a whole.
three-quarters
Three of the 4 equal parts.
equal parts
Parts that are exactly the same size.

What to watch for

Any two pieces are halves, even if unequal.
Help: Halves must be equal. Fold and match: do the two pieces lie exactly on each other?
¼ is bigger than ½ because 4 is bigger than 2.
Help: More cuts make smaller pieces. Cut a roti into 4: each piece is smaller than when cut into 2.
Half of 12 is 2 (the bottom number of ½).
Help: Half means share into 2 equal groups. 12 marbles → 6 and 6. Half of 12 is 6.
A quarter is bigger because 4 is more than 2.
Help: Look at the pieces, not the numbers. Cutting into 4 makes smaller pieces than cutting into 2.

Try this at home

  • Fold a paper roti so the two pieces lie exactly on each other: 2 equal parts, so each is ½
  • Fold a paper twice to make quarters
  • Half of 12 pencils: share into 2 equal groups, count one group
  • Two equal rotis cut differently

Quick questions to ask aloud

  1. True or false: A square folded from corner to corner makes two halves.
    Show answerTrue. The fold makes two triangles that are exactly the same size. Two equal parts are halves.
  2. A square is cut into 4 equal parts and 3 parts are coloured. What fraction is coloured? (¾ / ¼ / ½)
    Show answer3 out of 4 equal parts are coloured. That is three-quarters, ¾.
  3. Riya has 12 marbles. She gives half of them to Arjun. How many marbles does Arjun get?
    Show answerHalf means 2 equal groups. 12 marbles make groups of 6 and 6. Arjun gets 6 marbles.

How long does "Halves, Quarters and Fair Shares" take?

About 100 minutes in total, spread over 4 parts of 15–25 minutes each.

How can I help my child with "Halves, Quarters and Fair Shares" at home?

Work through a small example together, such as: Fold a paper roti so the two pieces lie exactly on each other: 2 equal parts, so each is ½; Fold a paper twice to make quarters. Then ask a quick question aloud: True or false: A square folded from corner to corner makes two halves.

What mistakes do children often make in "Halves, Quarters and Fair Shares"?

Any two pieces are halves, even if unequal. Fix: Halves must be equal. Fold and match: do the two pieces lie exactly on each other? ¼ is bigger than ½ because 4 is bigger than 2. Fix: More cuts make smaller pieces. Cut a roti into 4: each piece is smaller than when cut into 2. Half of 12 is 2 (the bottom number of ½). Fix: Half means share into 2 equal groups. 12 marbles → 6 and 6. Half of 12 is 6.
