Mathematics at Calmore Infant School

The aims of the national curriculum for mathematics are that all pupils:
• Become fluent in the fundamentals of mathematics
• Reason mathematically by following a line of enquiry
• Can solve problems by applying their mathematics

At Calmore Infant School, our approach to teaching, learning and assessing mathematics reflects these aims. We strongly believe that maths is best taught through the Concrete (real objects), Pictorial (drawn objects or images) and Abstract (numerals and symbols) approach. This is often referred to as the CPA approach.  In addition to this, children are encouraged to reason mathematically and develop their justifications and ability to prove ideas using mathematical language.

Maths at Calmore Infant is creative and taught through first hand, practical contexts that are relevant to the children’s interests. Children are encouraged to take risks, challenge themselves and make links across their learning in other areas of the curriculum.

Regular opportunities are provided to practice problems that become increasingly more complex over time, in order to become fluent with the fundamentals of mathematics. This allows our pupils to develop their conceptual understanding and the ability to recall and apply knowledge rapidly and accurately.

Children use a variety of real life resources to count, group and order such as sticks, acorns, buttons as well as more structured specialised mathematical equipment including  numicon, diennes and tens frames to support their learning. There is a strong emphasis on the use of multi-representation using a variety of mathematical resources. Each day, in addition to the taught maths sessions all of our children will take part in 4 rapid recall mental maths questions, focussing on shape & space, money, time and number. This ensures that children constantly recall, refresh and reinforce their learning.

CURRICULUM AREA MATHEMATICS
Purpose of Study:

Mathematics is a creative and highly interconnected discipline that has been developed over centuries. It is essential to everyday life, critical to science, technology and engineering, and necessary for financial literacy and most forms of employment. A high-quality mathematics education therefore provides a foundation for understanding the world and the ability to reason mathematically.

At Calmore, we aim to teach children to move fluently between the stages of concrete, pictorial and formal methods of representing mathematical problems. We have organised our programmes of study into distinct domains but will teach children to make connections across mathematical ideas to develop fluency, mathematical reasoning and competence in solving increasingly sophisticated problems.

Throughout our curriculum, children will apply what they have learnt in other subjects. We expect that the majority of pupils will move through the programmes of study at broadly the same pace. However, continuous assessment for learning will determine the security of children’s understanding and their readiness to progress to the next stage.

Children with secure understanding will be challenged through rich and sophisticated problems before moving onto new content. Those who are not confident with domain content will be supported to consolidate their understanding through additional precision teaching before moving on.

We aim for children to leave Calmore with a secure understanding of the mathematics curriculum content and a sense of enjoyment and curiosity about the subject.

National Curriculum Provision
Aims: The national curriculum for Mathematics aims to ensure that all pupils:

§ become fluent in the fundamentals of mathematics, including through varied and frequent practice with increasingly complex problems over time, so that pupils develop conceptual understanding and the ability to recall and apply knowledge rapidly and accurately.

§ reason mathematically by following a line of enquiry, conjecturing relationships and generalisations, and developing an argument, justification or proof using mathematical language

§ can solve problems by applying their mathematics to a variety of routine and non-routine problems with increasing sophistication, including breaking down problems into a series of simpler steps and persevering in seeking solutions.

Subject Content KS1

The principal focus of mathematics teaching in key stage 1 is to ensure that pupils develop confidence and mental fluency with whole numbers, counting and place value. This should involve working with numerals, words and the four operations, including with practical resources [for example, concrete objects and measuring tools].

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

By the end of year 2, pupils should know the number bonds to 20 and be precise in using and understanding place value. An emphasis on practice at this early stage will aid fluency.

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