SLIDE 2

In order to answers these types of calculation, we will have to practise three key skills.

Key skill 1:to understand what the word per cent means. Key skill 2:to recognise percentages as a fraction. Key skill 3:to be able to convert percentages to decimals.

SLIDE 3

Key skill 1:to understand what the word per cent means. We all see this sign everywhere but what does per cent or % mean?

SLIDE 4

Key skill 1:to understand what the word per cent means.

Per cent means 'out of 100'.

Watch Me

Look at my hundred square. How many parts are shaded? How many are not shaded? How would we write this as a fraction? Key skill 2:to recognise percentages as a fraction.

SLIDE 6

Watch Me

There are 5 squares shaded. There are 95 squares not shaded. We can write this as Key skill 2:to recognise percentages as a fraction.

There are _____ parts per hundred shaded. This is _____ %

Key skill 3:to be able to convert percentages to decimals.

This time we will work out what percentage is shaded and then use our knowledge of place value to convert the percentage into a decimal.

SLIDE 12

Watch Me

Key skill 3:to be able to convert percentages to decimals.

We have 20 parts of the hundred square shaded blue. We can write this as: 20 100

r 20%

We can then convert these into a decimal

0 . 2 0

We have shown 20 hundredths/20% but we also know that 20/100 is the same as 2/10.

SLIDE 13

Watch Me

Key skill 3:to be able to convert percentages to decimals.

We have 89 parts of the hundred square shaded blue. We can write this as: 89 100

r 89%

We can then convert these into a decimal

0 . 8 9

We can show 89 hundredths/89% as 0.89

SLIDE 14

Key skill 3:to be able to convert percentages to decimals.

We have 69 parts of the hundred square shaded blue. We can write this as: 69 100

r 69%

We can then convert these into a decimal

0 . 6 9

We can show 69 hundredths/69% as 0.69

SLIDE 15

SLIDE 18

Moving our learning on: For the first two questions, we need to consider what each

f the shaded sections represent.

On the third question, you will need to colour in 25% of the bar.
