1. Numeracy Information Session1

2. Session Aims The aims of this session are
To improve your understanding of Numeracy
To show you how to help your child with Numeracy

3. What is Numeracy? Estimation and rounding Number and number processes
Fractions, decimals and percentages
Money
Time
Measurement
Information handling

4. Estimation and Rounding
Estimation – Sometimes an exact answer is not required, a ball park figure is fine.
– Helps check the reasonableness of our answers.
Question
How far is Glasgow from Edinburgh? Choose the best estimate.
75 cm 75 m 75 km 750 km

5. Estimation and Rounding
Question
How far is Glasgow from Edinburgh? Choose the best estimate.
75 cm 75 m 75 km km
Discussion Points
Is it a big or small distance?
What unit would be reasonable for measuring larger distances?
The relationships between units e.g 100 cm = 1 m and 1000 m = 1 km
What mode of transport would be used?

6. Estimation and Rounding
Rounding – How accurate does the answer need to be?
Question
One day 75,241 football fans attended a game at Old Trafford.
Round this to the nearest 1000.
Question 2
The classroom is 7.5 m long. Round this to the nearest whole number.

7. Estimation and Rounding
Rounding – How accurate does the answer need to be?
Question 1
One day 75,241 football fans attended a game at Old Trafford.
Round this to the nearest 1000.
Question 2
The classroom is 7.5 m long. Round this to the nearest whole number.
Discussion Points
What place value does each digit represent?
Is it closer to 75,000 or 76,000?
What happens when the number is exactly half way between?

13. Fractions, Decimals and Percentages
Question
There are 16 pupils in class 2Y.
3 4 of them are girls. How many are girls?

14. Fractions, Decimals and Percentages

15. Fractions, Decimals and Percentages

16. Fractions, Decimals and Percentages
Question
Find 25% of 128
Find 30% of 140

17. Fractions, Decimals and Percentages
Pictorially
25% means 25 boxes out of 100
From the diagram 25% = 1 4
‘A quarter is half of half’
1 2 of 128 = 64
1 2 of 64 = 32

18. Fractions, Decimals and Percentages
30% = 3 x 10%
10% = 1 10
1 10 of 140 = 14
14 x 3 = 42

19. Time
Question
A train leaves Glasgow Central at 10:40am and arrives in Edinburgh at 12:10pm. How long was the journey?
An overnight ferry departs Dover at 23:15 The journey lasts 2 hours and 16 mins. What time does it arrive in Calais?

21. Final thought – the iceberg.
We’ve spoken today about what we’re doing in our respective departments; our hope is that it’s given you time to reflect on your own practice and has perhaps inspired some ideas.
