In addition to year 3 requirements, year 4 students will:

• Compare different measures, including money in £ and p.

• Estimate and calculate different measures, including £ and p.

• Read, write and convert between analogue and digital clocks.

• Convert time to the 24 hour clock.

• Solve problems involving time, duration of days and months.

Comparing measures - Money

What does it mean?

When we buy something from the shops or pay someone for work they have done, we use money. In this

country, money is measured in pounds and pence. Other countries use different currencies.

Money is measured using decimals. The decimal place separates the pounds and the pence.

Money Facts 100 x 1p = £1

50 x 2p = £1

20 x 5p = £1

10 x 10p = £1

5 x 20p = £1

2 x 50p = £1

Use the signs <, > and = to compare the amounts of money.

a) 4 x 5p ____ 20p

b) 50p ____ 2 x 20p

c) £1 ____ 25 x 2p

d) £1.50 ____ 50p + 50p

e) 20p ____ 3 x 10p

f) £1.20 ____ 6 x 20p

g) £2 ____ 3 x 50p

h) £1 ____ 11 x 10p

Money comes in two forms:

coins and notes.

Coins: 1p, 2p, 5p, 10p, 20p, 50p, £1 and £2

Notes: £5, £10, £20 and £50




What does it mean?

When we measure weight, we use grams and kilograms. There are 1000 grams in 1 kilogram.

We use weight to measure our own weight, the weight of ingredients in cooking and when we are posting a

parcel at the post office. Weighing scales are used to measure weight.

Can you think of any other times when we may need to understand weight?

Weight Facts

1000g = 1kg

500g = 0.5kg

250g = 0.25kg

100g = 0.1kg

---------------------------

2500g = 2.5kg

Use the signs <, > and = to compare the different weights.

a) 1500g ____ 1.2kg

b) 0.5kg ____ 400g

c) 3000g ____ 3kg

d) 1400g ____ 40kg

e) 0.7kg ____ 750g

f) 250g ____ 0.25kg

g) 2.7kg ____ 2600g

h) 1.25kg ____ 1300g

Other words that measure weight:

Tonne = 1000kg

Others include: stones, pounds (lbs) & ounces (oz)

What does it mean?

When we measure length, we use millimetres, centimetres, metres and kilometres. There are 100 centimetres

in 1 metre.

We use length to measure furniture, distance (how far away something is) and our height. Rulers can be used

to measure length.

Can you think of any other times when we may need to understand length?

Length Facts

10mm = 1cm

100cm = 1m

1000mm = 1m

1000m = 1km

---------------------------

2500m = 2.5km

Use the signs <, > and = to compare the different lengths.

a) 10cm ____ 1m

b) 150cm ____ 1.2m

c) 6.5km ____ 6500m

d) 2000mm ____ 2.2m

e) 0.5m ____ 200cm

f) 200cm ____ 0.2m

g) 600m ____ 0.5km

h) 220m ____ 3km

Other words that measure length: Miles

You may have seen this word on signs near roads.

Comparing measures - Length




Comparing measures - Capacity

What does it mean?

When we measure capacity, we use millilitres and litres. There are 1000 millilitres in 1 litre.

We use capacity to measure liquids such as orange juice and other drinks.

Can you think of any other times when we may need to understand capacity?

Capacity Facts 1000ml = 1l

1500ml = 1.5l

500ml = 0.5l

200ml = 0.2l

250ml = 0.25l

Use the signs <, > and = to compare the different measurements of capacity.

a) 1100mƖ ____ 1.2Ɩ

b) 0.5Ɩ ____ 450mƖ

c) 600mƖ ____ 6Ɩ

d) 2000mƖ ____ 2Ɩ

e) 0.9Ɩ ____ 900mƖ

f) 45Ɩ ____ 4500mƖ

g) 700mƖ ____ 0.7Ɩ

h) 3500mƖ ____ 3.2Ɩ

Other words that measure capacity: Pints & Gallons

You may have seen pints on milk bottles and

gallons at petrol stations.




Estimate the reading on the weighing scales.

Reading measures - Time

What does it mean?

When we read time from a digital or analogue clock, we use hours and minutes.

Can you think of any other vocabulary you may use involving time?

You will also need to be able to convert between analogue and digital time.

For example:

10:00 am

You will also be asked to convert to 24 hour

time but we will cover this later.

At the moment, we will use am and pm.

am = ante meridiem (morning)

pm = post meridiem (afternoon/evening)

Meridiem is a Latin word meaning midday.

So, am means before midday and pm means

after midday.

Write each time shown by the analogue clock into digital time.

: : :

: :

What does it mean?

The 24 hour clock is useful because you don’t need to use am and pm to clarify whether a time is in the morning

or evening.

Places such as hospitals and airports use this time regularly as it just consists of numbers, rather than numbers

and letters.

The 24 hour clock remains the same as digital and analogue times up to 12 midday and then instead of going

back to ‘1’ and changing to pm, we continue from 13:00 to 23:59.

Can you guess what number might follow 23:59?

Do you think it’s 24:00 or 00:00? Why?

Digital Time: AM/PM 24 Hour Clock

00:00 am (Midnight) 00:00

01:00 am 01:00

02:00 am 02:00

03:00.am 03:00

04:00 am 04:00

08:00 pm 20:00

09:00 pm 21:00

10:00 pm 22:00

11:00 pm 23:00

The 24 hour clock must consist of 4 digits.

04:00

But digital time involving am and pm can

consist of 4 digits or 3 digits.

4:00pm or 04:00pm

Perimeter of Rectangles

What does it mean?

In year 4 you will need to calculate the perimeter of a rectangle.

The perimeter is the measurement around the outside of the 2D shape.

When we calculate the perimeter of a rectangle, we add all of the sides together. In other words, two

times the length add two times the width. (2 x L) + (2 x W)
