The vision for the Mathematics Department at Corpus Christi is to provide an education which inspires pupils to be ambitious and reach their God given potential. To achieve this, we have developed a curriculum which supports and challenges all pupils, regardless of their ability, and ensures pupils are meeting the expected outcomes set out in the National Curriculum, and in some cases exceeding them. Teachers are highly skilled in adapting their teaching in response to feedback from pupils, allowing them to provide extra support or to stretch pupils further where appropriate. We believe it is our duty to make mathematics a subject which all pupils can access and enjoy, ensuring they are equipped to use mathematics after they leave school, whether that is using the basic numeracy skills required in adult life or studying mathematics at A level and beyond.

Mathematics is a subject which constantly builds on previous knowledge in order to make further progress which makes the sequencing of topics imperative. Our process to produce the sequencing of topics has been extremely rigorous, which has led to detailed schemes of work where topics are ordered in a way that is logical to build on prior knowledge. The schemes contain learning stages which are detailed and constantly adjusted through regular reflection from all members of the department.

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.

Mathematics is an interconnected subject in which pupils need to be able to move fluently between representations of mathematical ideas. The programme of study for key stage 3 is organised into apparently distinct domains, but pupils should build on key stage 2 and connections across mathematical ideas to develop fluency, mathematical reasoning and competence in solving increasingly sophisticated problems. They should also apply their mathematical knowledge in science, geography, computing and other subjects.

Decisions about progression should be based on the security of pupils’ understanding and their readiness to progress to the next stage. Pupils who grasp concepts rapidly should be challenged through being offered rich and sophisticated problems before any acceleration through new content in preparation for key stage 4. Those who are not sufficiently fluent should consolidate their understanding, including through additional practice, before moving on.

All pupils study the skills detailed in the national curriculum, with teachers adapting their teaching where necessary to provide extra support or to stretch pupils beyond the national curriculum where appropriate.

At Corpus Christi we believe that all pupils should be equipped with and supported in developing a high level of reading and literacy capability, as is required by each subject discipline. In mathematics, there are standards of mathematical oracy which each pupil must adhere to. In topics where poor oracy is a common issue, there are statements in the schemes which explains what pupils’ verbal answers should consist of. This is modelled by teachers and explained to pupils to continually reinforce the expected standard.

In mathematics, reading is differentiated to meet the needs of different ability groups, not only to support access to the curriculum but to also develop fluency and deepen understanding. Command words are a key issue in mathematics. Teachers therefore expose pupils to a variety of command words and ensure pupils understand what the instruction requires them to do. For example, you can ‘expand’ a bracket in algebra, but ‘multiplying out’ means the same thing. Such issues are best addressed by exposing pupils to a variety of instructions regularly.

Where there are examination questions that require a lot of reading, the emphasis is still on the command words involved. The reading age of pupils in each class will decide whether they are asked to read the question or have the question read to them. Either way, any key words or instructions in the question must be defined beforehand to provide context for the pupils. When doing this in mathematics, staff provide a definition which includes a mathematical calculation as an example. For instance, when discussing the word deposit, stating the definition ‘the amount paid to secure goods or services’ may not help pupils to understand what calculation is required. Instead, this definition would be followed by an example such as, ‘If you pay a deposit of £200 for an item which costs £1000, you will have £800 left to pay’. This way, as pupils read the question, they are already processing which calculations are needed at each stage to gain the final answer.

There are basic numerical skills that are vital to access the mathematics curriculum at each key stage. We refer to these skills as the ‘building blocks’ of mathematics. We have used evidence from research to identify which skills are the most important for each year group at Key Stage 3 and have produced numeracy assessments to test all pupils in those year groups on where, if any, the weaknesses are for each pupil. Once their weaknesses are identified, pupils are given targeted intervention from a Lead Teacher of Mathematics on those topics to ensure the obstacles to their learning are removed. Pupils are then retested after the sessions to assess the impact of the intervention.

‘The support that pupils receive to improve their numeracy skills has been particularly effective.’

Ofsted, 2019.

At Corpus Christi, we believe that high quality summative assessment must primarily enable pupils to demonstrate their knowledge and understanding acquired throughout the implementation of the planned curriculum. Subsequently, this will allow teachers to measure the progress made by pupils through the curriculum, in relation to learning outcomes set out in schemes of work. In measuring the extent to which pupils have acquired knowledge and a secure understanding, teachers will be able identify gaps in learning, to inform future teaching and planned interventions.

In mathematics, there are three key assessments in Years 7 – 10, one in each term of the academic year. At each of the three assessment stages, pupils are tested on what they have been taught since the start of that academic year to ensure knowledge is accumulated and retained throughout the curriculum. All assessments provide the correct amount of challenge for pupils, whilst ensuring their needs are met. This in turn leads to meaningful feedback for teachers to effectively address gaps in knowledge and consider the intervention required.

Following assessments, there is a clear and shared rationale for the awarding of progress grades in mathematics. In addition to summative assessment results, the awarding of progress grades will incorporate the use of formative assessment, enabling teachers to use their daily feedback through questioning and marking, to inform decisions related to progress grades.

In 2022, Corpus Christi achieved their **best ever **GCSE mathematics results, placing in the **top 20** schools in Lancashire for the progress made by the 2022 cohort.

In 2023, Corpus Christi, again, achieved their **best ever** GCSE mathematics results, with 70% of pupils achieving a grade 4 or above in the subject.

Our consistently strong teaching, high levels of engagement and improved outcomes in mathematics has led to us offering the AQA Level 2 Further Mathematics course to Higher Tier GCSE pupils in addition to their Edexcel GCSE Mathematics course. This offers pupils the opportunity to familiarise themselves with work that is completed during A Level Mathematics and strengthens their understanding of key concepts which can help to secure a grade 9 in their GCSE examinations. Furthermore, pupils receive UCAS points for this course, making it an extremely useful qualification when applying to university.

All of our highest achieving pupils in Years 7 to 10 are entered into the UKMT Mathematics Challenge each year with many pupils receiving certificates and being asked to enter further competitions by the organisation. This gives pupils the opportunity to compete against the best mathematicians in the country within their age group.

The Mathematics department also offer a weekly club to all pupils called ‘Mathletics’. This is consistently well-attended and gives pupils the opportunity to experience mathematics they may not encounter whilst studying the National Curriculum during lessons.
