At Leighton Middle School we believe that it is our duty to inspire young people to see the true beauty of maths in the wider world by bringing maths alive, and making it interesting and accessible to all. Mathematics is at the core of everyday life- from science and technology, to financial literacy and to support independence in future ambitions by developing cognitive function. We believe a high quality mathematics education is the foundation to increasing fluency in number skills, confidence in problem solving skills and developing independent learners who have tenacity when faced with a challenge.
Our aims are to develop the ability to move with fluidity between mathematical concepts, build connections between the skills learnt and to recall and apply knowledge to problem solve and reason.
Students are supported in developing mathematical language to explain, justify and debate to follow a line of enquiry. Through modelling, we show clear links between worded questions and mathematical processes. By celebrating a Maths Word Wall, we use complex terminology to encourage ambition to understand and apply the terms. During reasoning questions, students are asked to give written responses, to ensure clear interpretation of the maths and the literacy, in tandem. This helps the development of literacy skills to apply across the curriculum.
The mathematics department is committed to progressing each student at a rate that is supportive and challenging, ensuring the self-confidence of each student is built upon to prepare them for some of the more pure mathematical concepts. Although the expectation is that students would move through the program of study at approximately the same rate, we recognise the importance of securing knowledge, facilitating opportunities to practice and solidify understanding before moving on.
To achieve our intentions, we implement the following.
- Our program of study has been adapted from White Rose maths at KS2 and MyMaths at KS3. The program is bespoke to LMS to ensure a smooth transition from their lower schools and into their upper schools through regular communication with both. A little and often approach is employed to interleave core skills throughout the year, to increase that fluency in number skills, whilst also fine tuning these skills to move the topic knowledge on.
- Students are placed in class groups according to various criteria. This is a combination of teacher observations, assessment data, KS1 data and personality styles. By placing the students in groups, they are with students who work in a similar pace and style and so this personalises the teaching and learning experience for both teacher and student. Personalised teacher feedback is also increased as a result of smaller groups.
- Knowledge and skills are delivered through use of mathematical understanding and not by copying a process. Students are encouraged in lessons to justify their answers, analyse the validity of their response and to question the answers of those around them, in a polite and constructive manner.
- Class teaching includes modelling answers in various ways. This may be worded in steps, bullet points, correct calculations or in diagram form. This expands the students' understanding of a skill from various approaches and develops their depth of knowledge.
- Students are encouraged to take pride in their achievements and to ensure presentation of all work is of a high standard. Homework is set to increase this independence further. This prepares students to take ownership of their educational journey, through time management and recalling and applying knowledge outside of the classroom, supporting independent learning.
- Intervention is available for students who require additional support and this is personalised to build self-confidence as well as knowledge and skills.
- At LMS we provide a wide and rich set of experiences throughout the year groups to apply and improve numeracy outside of the classroom. This enrichment is in the form of games clubs, sporting links, investigation afternoons, day trips, maths challenges and timetables battles.
Students of all abilities show a great drive and determination to improve their mathematical skills, accepting and working with the support put in place to help them strive towards personal excellence. During their journey, students become more numerically fluent and are able to recall and apply knowledge when revisiting and moving topics on.
Students come to LMS below the national average, according to standardised scores and they leave ready to take the next step in their mathematical journey; the majority above the national average.
Teachers obtain an understanding of students’ strengths and areas to develop through accurate teacher assessment and formal assessment data. As a result, class time is focused on maximising the benefit to the student.
At Leighton Middle School mathematics is a well-liked subject. Students become more inquisitive during their time with us, developing skills beyond just number but also increased ambition to progress in a way that is personal to each individual student. Pupil panels report a love of the challenge in lessons and a willingness and understanding on how to work both autonomously and collaboratively- with both students and teachers.

The Rule of Law
Students listen and discuss each other’s ideas, working in learning partners and investigating in groups. We discuss the importance of opinion and the rules of questioning when designing questionnaires and collecting data.
Students follow class rules safely during tasks and activities to benefit everyone, as well as understanding the consequences if rules are not adhered to.
Students work within boundaries to make a safe and personal choice from a given selection during activities that require a self-reflection upon their own individual level of confidence in each topic area.
Students behave appropriately, allowing everyone involved the opportunity to work to the best of their ability. They take turns, sharing equipment, reviewing each other’s work respectfully and working collaboratively on projects whilst helping others. They learn from and with each other.

Coaching opportunities are utilised to extend the application of a skill through peer-to-peer support. Listening and engaging with others are placed hand in hand with individual mind set and tenacity.
