1. Year 2 Maths Parents’ Workshop Canford Heath First School
March 2013

2. Purpose of this evening
To help you understand the progression in teaching maths in KS1
To show the ‘informal’ methods used for x ÷
To share the vocabulary used
To share some of the games and resources used, including those on the internet
To suggest ways you can help your children

3. How has Maths changed ……….
children’s recall of number facts has become more accurate and faster
children are more aware of the strategies they use to calculate
they use vocabulary correctly
they are more confident about maths
maths is more fun!

4. The aim for our children
The aim is for children to do mathematics in their heads, and if the numbers are too large, to use pencil and paper to avoid losing track.
To do this children need to learn quick and efficient methods, including appropriate written methods.
So, mathematics is foremost an activity of the mind and written calculations are an aid to that activity.
Learning written methods is not the ultimate aim.

5. Areas of Maths NUMBER place value addition and subtraction
multiplication and division
fractions
GEOMETRY & MEASURES
shapes
position, direction and motion
measures
DATA
pictograms, tables and graphs

6. Progression in Maths Reception and Year 1 Very practical and mental
Lots of counting, songs and games
Based in play, especially in Reception
Reception teaching and learning is based on numbers 1 – 20 and developing their understanding of the number system.
Year 1 – working with numbers to 20 initially, moving on to 100
Resources: objects, number lines, number bean bags ,
fish cards (T/U), games, 100 squares, computers

7. Place value Year 1 Read and write numerals from 0 to 20, then beyond
Use knowledge of place value to position these numbers on a number track and number line 
Year2
Read and write two-digit and three-digit numbers
Explain what each digit in a two-digit number represents, including numbers where 0 is a place holder
partition two-digit numbers in different ways, including into multiples of 10 and 1 
Year 3
Read, write and order whole numbers to at least 1000 and position them on a number line
Partition 3 digit number into multiples of 100, 10 and 1 in different ways
Resources – ruler, arrow cards, hundred square, number fans,
dienes apparatus

8. Tens Units
3 4
Partitioning 30 4
34 =
34 =

9. Addition
On a Number Line
8 + 5 = 13

10. First counting on in tens and units. 34 + 23 = 57
+10
+10
+ 3

11. Adding the tens and units in separate jumps 34 + 23 = 57
+20
+ 3

12. Adding the tens and units in separate jumps and ‘bridging’ through.
= 61
+20
+ 6
+ 1

13. Addition
By partitioning: = =
= 35

14. Vocabulary
Add, addition, and, count on, plus, sum, more, altogether, increase
Addition is counting on and can be done in any order. ie =
It tends to easier to put the BIGGEST number first

15. Subtraction
6 – 3 =

16. Counting back in separate jumps of tens and ones.
47 – 23 = 24
-10
-10 -1 -1 -1 37 47 24 25 26 27

17. Subtracting in jumps of tens and units. 47 – 23 = 24
- 20
- 3 47 24 27

18. Counting on
If the numbers involved in the calculation are close together or near to multiples of 10, 100 etc, it can be more efficient to count on, e.g. 204 – 198 = 6.
43 – 35 =
204 – 198 = +2 +4
198
204

19. Vocabulary
Take away, subtract, subtraction, count back, minus, less, decrease, difference between
Find the difference between numbers by counting up from the smaller number.
The biggest number comes first in the calculation. The order can’t be changed.

20. Multiplication Repeated addition
3 times 5 is = or 3 lots of 5 or 5 x 3 5 5 5

21. Showing multiplication as an array.
3 x 5 = 15
3 rows of 5
5 x 3 = 15
5 columns of 3

22. Repeated addition 0 6 12 18 24 Drawing a number line.
4 times 6 is = 24
or 4 lots of 6 or 6 x 4
6 lots of 4
vid

23. 13 x 5 = 65 10 3 Partitioning 10 x 5 = 50 3 x 5 = 15 50 + 15 = 65
Partition the 2 digit number to be multiplied into TU
13 x 5 = 65
10 x 5 = 50
3 x 5 = 15
= 65 10 3
Children also need to be encouraged to use what they know to work out what they don’t know. E.g. 1 x6 = 6 so 100 x 6 = 600 etc

24. Vocabulary
Multiply, multiplication, times, lots of, groups of, multiple, double, array, repeated addition
Year 1 – recalling doubles to 10, counting on and back in 2’s, 5’s and 10’s
Year 2 – 2x, 5x and 10x tables and division facts
Year 3 – 2x, 3x, 4x, 5x, 6x and 10x tables and division facts

25. Division
In EYFS and Y1, Children will understand equal groups and share items out in play and problem solving. They will count in 2s and 10s and later in 5s.
12 shared into 3 groups

26. 3 12 ÷ 3 = Children will develop their understanding of division
and use jottings to support calculation 3

27. 12 ÷ 3 = 12 3 6 9 Showing this on a number line.
From the group of 12 stickers, you are sharing out to the 3 girls, by taking away 3 stickers at a time. Repeated subtraction. -3 -3 -3 -3 12 3 6 9

28. Using Symbols to stand for unknown numbers to complete equations using inverse operations
 x 5 = x  = 18
5 x  =  x 3 = 18
20 ÷  = ÷ 3 = 
Children need lots of opportunity to practise
and develop their understanding of these
relationships whenever possible.

29. 7 6 7 6 0 7, 6 0 0 Th H T U Multiplying by 10 or 100
Knowing that the effect of multiplying by 10 is a shift in the digits one place to the left.
Knowing that the effect of multiplying by 100 is a shift in the digits two places to the left.

30. Dividing by 10 or 100
Knowing that the effect of dividing by 10 is a shift in the digits one place to the right.
Knowing that the effect of dividing by 100 is a shift in the digits two places to the right.
Th H T U
7, 6 0 0
7 6 0

7 ÷ 10

31. Vocabulary
Group, divide, division, divided by, divisible, factor, share, half, halve, remainder

32. Using and applying their knowledge and skills is so important
Applying skills across all areas of learning
Word problems
Real life experiences and problems
A range of contexts – measures, money-eg. Giving change, finding different ways to make a total
Explaining and describing thinking
Using and applying their knowledge and skills is so important

33. How you can help…
Mental maths practise especially number bonds, simple addition/subtraction facts, 10 more and less, doubles and halves
Board games and games involving dice and numbers e.g. snakes and ladders, cards, dominoes
Shopping - prices, weights, shape hunting, comparing sizes
Cooking - involving weighing and measuring
Money - costs, coin recognition, giving change
Ask them to show you how to do calculations, get them to explain the method.
Counting
Educational internet games
Telling the time/ months/ days of the week
Make it fun!
