Maths Statement of Intent for CMS

Mathematics is all around us; whether you are a scientist or a musician, a hairdresser or an engineer, everyone uses maths in their day to day life.  And, although we may not notice, it is also present in nature, from the radial symmetry of falling snowflakes to the Fibonacci spiral present in a nautilus shell.

Mathematics helps us make sense of the world and create order. It develops many personal qualities such as problem solving, creativity, critical thinking, analytical and reasoning skills and even communication skills. At Chantry Middle School, it is our aim that all children leave us with a secure understanding of the basics and the ability to reason and problem solve, drawing upon a wide range of knowledge quickly and accurately. 

Age Related Expectations

We have a firm belief that in order for children to become confident mathematicians, they need to have a secure understanding of essential maths skills which is why our year 5 and 6 curriculum is designed to build upon the foundations from first school with a focus upon these skills.  The main focus of teaching in upper Key Stage 2 is to ensure that pupils extend their understanding of the number system and place value to include larger integers and decimals, becoming fluent in calculating with mental and written methods. We aim to develop the connections that pupils make between multiplication and division with fractions, decimals, percentages and ratio.

Key stage three builds upon the knowledge developed in key stage two, starting with a grounding in algebra which pupils use and apply within other areas of maths. During years 7 and 8, pupils extend their calculation skills to incorporate negative numbers and inequalities before deepening their understanding of fractions decimals and percentages. They extend their understanding of shape and measure to explore geometric reasoning including circles, explore internal and external angles and those found on parallel lines and understand how to find the perimeter and area of a growing range of shapes. They will encounter probability for the first time and be introduced to different methods of interpreting and presenting data.

We have designed our curriculum to have high expectations for all; we aim to give all learners the tools and knowledge they need to succeed in later life, be that in qualifications achieved or in future careers.

Maths homework is centred around retrieval practice which helps consolidate pupils’ knowledge and understanding. We use Sparx maths to provide personalised homework for every child. Sparx creates homework tasks which are aligned with our curriculum, tailoring each question to the strengths and needs of individual pupils. The practice is both challenging, and achievable so that all pupils achieve success. Teachers receive detailed feedback on performance of pupils as a class and at an individual level which further informs the teaching and learning in the classroom. At KS2, it is anticipated that homework will take approximately 30 minutes a week to complete, whereas at KS3 this is increased to an hour.  This short video includes further information about Sparx. 


We assess pupils regularly using a wide range of methods that help teachers develop an understanding of pupils strengths and areas for development. Throughout topics, questioning, quizzes and short tests are used to monitor pupils’ growing understanding. At the end of a unit of work, a unit test will be undertaken which assesses the key components of knowledge and skills specific to that unit. Summative assessments are used at the end of each term to assess pupils’ ability to recall information, and reason and problem solve. Due to the fundamental nature of calculation, regular arithmetic assessments also take place each half term.

Resources for Parents

Just as it is for children, maths anxiety can be a real struggle for parents. But the more positively you approach the subject, the more confident you and your child will become.  Even if you find maths difficult, it’s still entirely possible to gain a better understanding. You can help guide your children to success. The resources below will provide you with ideas, tips and resources to support your child.

  • The Oxford Owl website features activities, simple ideas, top tips and eBooks to help your child with their maths at home. 
  • The National Numeracy website offers advice, ideas and materials for parents to help their children feel good about numbers.
  • Maths is Fun is an American website which explains maths concepts in easy language, plus puzzles, games, worksheets and an illustrated dictionary.

The maths work your child does at school may look different to the kind of work you remember from when you were at school. Pupils are initially encouraged to work mentally where possible, using personal jottings to support their thinking. By the time pupils start middle school, they will beginning to explore the written methods many adults learned ‘by heart’.

The calculation policy shows the stages your child will go through when learning to add, subtract, multiply and divide numbers. It will explain key methods used and share some of the vocabulary your children will be using in relation to their learning.
