Supporting Your Child
in Maths
March 2014 – J Cartwright
Areas of Maths
Maths is split into 4 main parts:
Ma 1 – Using and applying
Ma 2 – Number
Ma 3 – Shape, space and measure
Ma 4 – Handling data
Number makes up 50% of what the children need to know.
APP
(Assessing Pupils’ Progress)
• APP is used to collect evidence of what
skills and knowledge children
demonstrate in class.
• Provides an opportunity to collect
evidence during practical activities and
games.
• We use these grids to set individual
targets.
New Target Grids
We will now be using the following target
grids throughout the school. They will be
stuck into the front of the childrens’ maths
books. They are based on the APP grids
used by teachers to assess children and
the childrens’ individual targets will be
taken from these grids. (Note – they only
cover Number and not the other areas of
maths).

Addition
Begin with place value – children must know the value of each digit.
At level 2 we use the expanded version of the addition method:
e.g. 54
+27
11
70
81
54 + 27 = 81
Then we move on to the compact version of the addition method:
e.g.
67
+24
91
1
67 + 24 = 91
At level 3 we use the addition method to add 3 digit numbers.
We also begin to add decimals (where bridging is not required)
146 + 128 =
1.32 + 1.25 =
e.g. 146
+128
274
e.g. 1.32
+1.25
2.57
1
At level 4 children would be expected to use the addition
method to add decimals which DO require bridging.
Subtraction
We teach children different methods and allow them to choose
their preferred methods when solving problems.
We find the difference between 2 numbers using a number line:
81 – 57 =
+20
+3
57
+1
60
20 + 3 + 1 = 24
80
81
We also teach the subtraction method:
4
1
156
- 39
117
156 – 39 = 117
Multiplication
At level 2 we use repeated addition to
solve multiplication sums or problems.
e.g.
8X4=
8+8+8+8=
At level 3 we need to be able to multiply a 2digit number by 2, 3, 4, 5 or 10.
To do this we use the multiplication method:
23 X 4 =
e.g.
X 20
3
4 80
12
80
+12
92
At level 4 we also need to be able to multiply a simple
decimal by a single digit:
8 X 3.8 =
X
3.0
0.8
8
24.0
6.4
24.0
+ 6.4
30.4
Division
At level 2 we use repeated addition to solve
division sums and problems:
e.g.
16 ÷ 4 =
0
4
8
12
16
At level 3 we divide 2-digit numbers by 2, 3,
4, 5 and 10.
To do this we teach 2 different methods and
allow children to choose their preferred
method when solving problems:
172 ÷ 5 =
3 4 r2
5 172
10 X 5
50
122
10 X 5
50
72
10 X 5
50
22
4X5
20
2
10
10
10
+ 4
34 r2
Or: 172 ÷ 5 =
3 4
5
2
1 7 2
r2
When teaching division we always teach it as
how many equal parts can fit into that
number.
e.g. 45 ÷ 5 = how many 5’s go into 45?
count in 5’s until we reach 45.
the answer is 9.

X tables
Doubling
Halving
X tables
Children can never do too much X tables practise!
If they have been set a X tables to learn as a target
this includes not only counting in that number but also
answering quick fire questions in random order.
Effective ways of learning include clapping and
counting, quick fire questions, singing songs and
playing games such as Multiple Madness (Maths Zone),
pennies in a jar, jumping multiples.
At level 2 we focus on 2’s, 5’s and 10’s.
At level 3 we also need to know 3’s and 4’s.
At levels 3 and 4 we move on to 6’s, 8’s, 9’s and 7’s.
Doubling and halving
If children can not double or halve a 2-digit
number in their heads, we encourage them to
use arrows:
3 4
60
8
4 4
60+8 =68
20
2 20+2=22
Problem Solving
Huge importance in children being able to
apply the skills they have learnt.
1 step problems
e.g. Amy had 3 boxes of eggs with 6
eggs in each box. How many eggs
altogether
Children need to recognise what operation to use (multiplication or
repeated addition), then decide what numbers to multiply, then
work out the answer.
6 X 3 = 18
or
6 + 6 + 6 = 18
2 Step problems:
e.g.
Amy has 3 boxes of eggs with 6 eggs
in each. She eats 4 of the eggs, how
many does she have left?
Step 1: 3 X 6 = 18
Step 2: 18 – 4 = 14
