# Mathematics

At Riverbridge Primary School we have fully adopted the New 2014 National Curriculum for mathematics. In line with the new guidance we strongly believe in the delivery of a high-quality mathematics education which provides a foundation for understanding the world, the ability to reason mathematically, an appreciation of the power of maths, and a sense of enjoyment and curiosity about the subject.

As a school we aim to help our learners to become:

- fluent in the fundamentals of maths
- reason mathematically
- solve problems

## Key Stage 1

**Overview of Key Stage 1 – Years 1 and 2**

The principal focus of Mathematics teaching in Key Stage 1 is to ensure that pupils develop confidence and fluency when counting and calculating using whole numbers. This should be based on a secure understanding of place value and the number system. Pupils will encounter mathematical problems expressed in both numerals and words, involving all four operations; addition, subtraction, multiplication and division. All pupils will be encouraged to use practical resources to support their learning.

At this stage, pupils will develop their ability to recognise, describe, draw, compare and sort different shapes and use the related vocabulary. Pupils will use a range of measures to describe and compare different quantities such as length, mass, capacity/volume, time and money.

Pupils should read and spell mathematical vocabulary, at a level consistent with their increasing word reading and spelling knowledge at Key Stage 1.
