We all use maths every day, often without realising it. We
believe that every child can develop the numeracy skills
they will need, both at school and throughout their lives.
Helping your child feel confident about maths now gives
them a head start.
Building strong foundations in Year One
 Place
Value
 Counting
 Number
Bonds
 Developing
a sense of number
Place Value

Knowing the value of each digit in a number

Understanding of place value underpins all other number
and calculation work.

Developed through games and songs.

Counting at home

Counting games
Whack a mole

Sing counting songs and use counting in meaningful
ways in games, such as Hide-and-Seek.


Number Bonds (Number facts)
A
pair of numbers that add up to make another
number, e.g. 3 + 2 = 5, 1 + 4 = 5
 By
the end of Year One, children need to know
all of these number bonds off by heart:
2, 3, 4, 5, 6, 7, 8, 9 and 10
2 =
3 =
4 =
1 + 1
5 =
4 + 1
3 + 2
8 = 7 + 1
6 + 2
5 + 3
4 + 4
2+ 1
6 = 5 + 1
4 + 2
3 + 3
9 = 8 + 1
7 + 2
6 + 3
5 + 4

Addition and Subtraction facts
 If
I know that
3 + 2 = 5, then I know that
5 – 3 = 2 and 5 – 2 = 3.
 If
I know that 2 + 8 = 10, then I know that
10 – 8 = 2 and 10 – 2 = 8.

Get confident at Numeracy!

Be positive
Don’t say things like ‘I can’t do maths/numeracy’.

Praise effort
This shows that by working hard they can always improve.

Talk maths!
Talk about and do everyday maths together. Little and often is best.
