Week 8, Day 4 Find non-unit fractions of quantities (1)

Each day covers one maths topic. It should take you about 1 hour or just a little more.

1. Start by reading through the Learning Reminders.

They come from our PowerPoint slides.

2. Tackle the questions on the Practice Sheet.

There might be a choice of either Mild (easier) or

Hot (harder)!

Check the answers.

3. Finding it tricky? That’s OK… have a go with a

grown-up at A Bit Stuck?

4. Have I mastered the topic? A few questions to

Check your understanding.

A Bit Stuck?Choccie quarters

Work in pairs

© Hamilton Trust

Learning outcomes:• I can find ¼, ½ and ¾ of amounts (whole number answers).• I understand that 2⁄4 is the same as ½.• I am beginning to see that we can share numbers in the 4 times table into quarters

(whole number answers).

Things you will need:• A pencil• Cake picture• 40 chocolate buttons or counters

What to do:

Share the chocolate buttons between the quarters on the cake to help you to answer

these questions.

¼ of 8 is ¼ of 28 is

½ of 8 is ½ of 28 is

¾ of 8 is ¾ of 28 is

¼ of 16 is ¼ of 32 is

½ of 16 is ½ of 32 is

¾ of 16 is ¾ of 32 is

¼ of 24 is ¼ of 40 is

½ of 24 is ½ of 40 is

¾ of 24 is ¾ of 40 is

S-t-r-e-t-c-h:Think of other numbers of chocolate buttons that you could place on the cake, so that there is the same number of buttons in each quarter. You are not allowed to cut up any buttons!

Answers

Find 1 8# , then 3 8# and then 5 8# of 24.

3, 9 and 15 respectively. Have children remembered the functions of the denominator and numerator correctly?

Write the missing numbers: 1 3# of 15 is 5

2 3# of 21 = 14

3 5# of 20 = 12

2 5# of 10 = 4

If children are struggling with these then model with counters.

Which is bigger: 2 5# of 35 or 3 8# of 32? 2 5# of 35 since it is 14. 3 8# of 32 is 12. Watch for children who have only found

the unit fraction each time, they may still think the first fraction is bigger.

Challenge Tom finds that 20 stickers fit in his book. This is 1 4# of his sticker collection. How many stickers does he have in all? 80.
