*This quiz addresses the requirements of the National Curriculum KS1 Maths and Numeracy for children aged 6 and 7 in year 2. Specifically this quiz is aimed at the section dealing with finding fractions of lengths. *

Understanding fractions of length means firstly being able to halve or quarter by dividing by 2 or 4. Applying this to a unit of measurement may mean having to convert units - for example, if asked to find half of 1m, it would first be sensible to recognise that 1m = 100cm.

Playing this quiz will help your child understand how to find fractions of length.

Question 1

I measure my pencil on Monday and it is 16cm long. By Friday, it is only half of this length. How long is my pencil on Friday?

10cm

8cm

4cm

12cm

Half of 16 is 8, so the pencil must be 8cm long

Question 2

John walks 4 km to school. A ^{1}⁄_{4} of the way to school is a sweet shop. How far is it from John’s home to the sweet shop?

1 km

2 km

4 km

8 km

To find a quarter of a number, divide it by 4 - or half it and half it again

Question 3

A roll of tape measures 12m. I use ^{3}⁄_{4} of the tape. How much is left?

5 m

3 m

2 m

6 m

To find a quarter, divide 12 by 4 to get an answer of 3. If ^{1}⁄_{4} is 3, then ^{3}⁄_{4} is 9, leaving 3m of tape

Question 4

Harry is 120 cm tall. His little brother is half this height. How tall is Harry’s brother?

40cm

60cm

80cm

240cm

Half of 120 is 60

Question 5

Cubes measure 3cm each. I make a row of 10 cubes. Then I break the row in half. How long is each half of the row?

10cm

12cm

15cm

13cm

3cm x 10 = 30cm. Half of 30 is 15

Question 6

Sam walks 1 km to school every day. She meets her best friend exactly halfway. How far does Sam walk before she meets her friend?

250m

500m

2km

100km

1 km is 1000m. Half of 1000 is 500

Question 7

What is ^{1}⁄_{4} of a kilometre?

25cm

25m

250cm

250m

1 km is 1000m. Half of this is 500m, so a quarter is 250m

Question 8

I have a piece of ribbon which is 64cm long. I cut it in half - how long will each piece be?

40cm

23cm

28cm

32cm

Half of 64 is 32

Question 9

Jim ran 1^{1}⁄_{2} km. Ben ran 1^{1}⁄_{4} km. How much further did Jim run than Ben?

1 km

Two quarters are the same as a half

Question 10

May grows her sunflower to 80cm. Jake's is only ^{1}⁄_{4} of this height. How tall is Jake's sunflower?

80cm

60cm

40cm

20cm

To find a quarter, divide by 4
