A unit fraction is a fraction with a numerator of 1.
L.O. To find unit fractions of amounts. A unit fraction is a fraction with a numerator of 1. 1 2 Numerator (how many) Denominator (what kind) 1 3 1 100 1 25 1 5 1 50 1 7 1 1 4 1 20 1 8 1 10
4
L.O. To find unit fractions of amounts.
We can find unit fractions of a set of objects by equal sharing. There are eight fish. How can we find half? To find we divide into 2 equal groups. 1 2 of 8 = 4 because 8 ÷ 2 = 4 1 2
5
L.O. To find unit fractions of amounts.
There are 15 teddy bears. How can we find ? 1 5 To find we divide into 5 equal groups. 1 5 of 15 = 3 because 15 ÷ 5 = 3 1 5
6
L.O. To find unit fractions of amounts.
There are 18 footballs. How can we find ? 1 3 To find we divide into 3 equal groups. 1 3 of 18 = 6 because 18 ÷ 3 = 6 1 3
7
L.O. To find unit fractions of amounts.
What is of 10? 1 5 What kind of fraction is this… how many groups should we share into? of 10 1 5 What should we do next? Predict how many counters will be in each section. of 10 = 2 1 5

Use you multiplication grids to help you.
L.O. To find unit fractions of amounts. TB1, Page 32. Qus Use you multiplication grids to help you. Write a division number sentence for each question. e.g. 1. 1/3 of 9= 3 > ¼ of 8 = 2 9÷ 3 = ÷ 4 = 2 > Greater than < Less than TB1, Page 32. Qus 1-12. Use your multiplication grids to help you. Write a division number sentence for each question. e.g. 1. 1/3 of 24 = 8 24 ÷ 4 = 8 Draw fraction strips to help you answer these questions: 1/3 of 21= ¼ of 32= 1/5 of 15 = ½ of 12 = 1/6 of 18 = Work with Miss to complete your worksheet.

12
A unit fraction is a fraction with a numerator of 1.
L.O. To non-unit fractions of amounts. A unit fraction is a fraction with a numerator of 1. 1 2 Numerator (how many) Denominator (what kind) 1 3 1 100 1 25 1 5 1 50 1 7 1 1 4 1 20 1 8 1 10
13
L.O. To non-unit fractions of amounts.
There are 30 sweets in a tube and 1/5 of the sweets are yellow. How many sweets are yellow? What kind of fraction is it? How many groups do we need to divide the sweets into? of 30 = 6 1 5 Because 30 ÷ 5 = 6
14
L.O. To non-unit fractions of amounts.
A non-unit fraction is a fraction with a numerator of any number apart from 1. 2 4 Numerator (how many) Denominator (what kind) 5 10 2 5 4 16 2 25 100 2 3 5 6 8 12 3 9 4 7 10 25
15
There are 24 sweets in a tube and of the sweets are green.
How many sweets are green? 2 3 What kind of fraction is this? How many groups do we need to divide the sweets into? How many parts are we looking at? How many groups do we need to count? of 24 = 16 2 3
16
2 3 L.O. To non-unit fractions of amounts.
There are 24 sweets in a tube and of the sweets are green. How many sweets are green? 2 3 2 3 Denominator (what kind) The denominator tells us what kind of fraction it is. This fraction is a third, so we need to divide into 3 equal groups. Numerator (how many) The numerator tells us how many of those groups we need. For this fraction, we need to count the number of sweets in 2 of the groups.
17
There are 24 sweets in a tube and of the sweets are red.
L.O. To non-unit fractions of amounts. There are 24 sweets in a tube and of the sweets are red. How many sweets are red? 2 6 2 6 of 24 = 8
