Place Value
Place value is of fundamental importance to children's
understanding of maths and without a solid grasp of it,
children will find it very difficult to move on.
3
Place Value - Each digit in its right place gives a number
its value.
4
Place value - Partitioning
Separating a number into tens and ones
75
70
5
70 + 5 = 75
5
Addition - The Hundred Square
Jumping
down in 10s
and
jumping
sideways in
ones
6
Addition - with a confident understanding of place
value, children can group tens and units for addition
35 + 24 = 59
30
5 20
4
30 + 20 + 5 + 4 = 59

Adding on a numberline
In year 2 we progress to a blank number line
Adding on a blank numberline
1. Write your number sentence and draw BNL.
2. Put the bigger number first.
3. Partition the smaller number.
4. Add the tens and the units.
5. Write your landing numbers.
6. Complete your number sentence.
35 + 24 =

+ 10

Have a go: 42 + 25

Subtraction - using partitioning to group
tens and units
85 - 24 = 61
80
5 20
4
80 - 20 = 60
5-4=1
60 + 1 = 61

Subtraction on a numberline
Take away on a blank numberline
1. Write your number sentence and draw your BNL.
2. Put the bigger number at the end.
3. Partition the smaller number.
4. Take away the 10's and the units.
5. Write your landing numbers.
6. Complete your number sentence.
45 - 27 = 18

Multiplication - grouping sets of objects repeated addition
2 lots of 5 = 10
6 groups of 2 = 12
9 x 10 = 90
4 x 5 = 20
5 x 4 = 20
11
Multiplication - arrays (pictoral)
4 x 5 = 20
5 x 4 = 20
12
Multiplication - The Hairy Spider Method!
6 x 2 = 12
13
Multiplication - BNL
3x2=6
1. Write number sentence
2. Draw number line and put 0 at the beginning
3. Circle number of jumps and draw your jumps
4. Write in number you are adding each time
5. Write landing numbers
6. Complete the number sentence
