Maths
• What does Maths mean to you?
• When do we use it?
What Maths means to us!
• At Churchdown Village Infant School we teach Maths so
that every child will have confidence and a secure
understanding of mathematics.
• We believe that this enables a solid base which will develop
into life long skills.
Gill Western CVIS
How do we do this?
We teach the children:
• to recognise numbers and know their value, including
money
• calculation
• mathematical language
• shape, space and measure
Gill Western CVIS
Teaching for Progression
• Reception
• Year One
• Year Two
Reception –Year 2
We teach the children 4 Basic Operations
•
•
•
•
•
Add
Subtract
Multiply
Divide
All 4 operations are taught through exploration e.g. playing
games, posing practical problems based on real life situations..
Gill Western CVIS
These are:
• play based activities :
• oral counting
• action rhymes & songs
• stories
• ICT games
•
Exploration
Gill Western CVIS
Mathematical Language
We also believe that one way to break down barriers which
prevent learning in maths is to focus on mathematical
language whilst also teaching the basic skills.

equally with my sister! How many will we have each?
Noah invites Max and Harry to play. He has 15 cars and he
has to share them equally. How can he do this? How many
cars will Noah have? How many cars will Harry and Max
have?
Is it fair?
