Mathematics

‘Some people think maths is all about getting the right answers, when it’s actually about asking the right questions.’ – Eugenia Cheng

Our curriculum is designed to provide our students with opportunities to question, investigate, make conjectures, generalise, and discover connections, as they develop understanding of mathematics and its application to other subjects and the real world. We believe that developing a conceptual and relational understanding of why maths “works” rather than just following a set of instructions leads to a greater understanding and confidence in maths. Our curriculum seeks to develop students’ understanding of mathematical concepts and structures, alongside providing sufficient practice to attain fluency. This approach enables our students to see mathematics as an interconnected subject, to make links between different topics, explore different representations, and to understand how mathematics relates to other subjects they study. The topics studied are used to develop use of correct mathematical vocabulary, fluency and mathematical reasoning.

Problem solving is at the heart of mastering mathematics. Students are provided with regular opportunities to develop their problem-solving skills and are introduced to frameworks and strategies which will support them in solving increasingly complex problems.

Mathematics lessons are intended to engage students in mathematical conversations, the exploring of misconceptions and purposeful practice. Students are taught to recognise that there are often different methods to solving a mathematical problem, and that the ability to choose an efficient method is an important skill. Our ambition is to develop curious, successful and confident learners who have an enjoyment of, and a positive attitude towards mathematics. We work to ensure that all learners will be equipped with the maths skills they need to support them through life, in making a positive contribution to society, and in progressing on to the next stage of their career pathway.

Estimation.

It is essential that students are aware of the general structure of the place-value system as being based on powers of ten and begin to see how this naturally extends to decimals. This learning will support students’ work on significant figures and standard form, as students who can express numbers in these different ways are more likely to have a feel for the size of such numbers and where they fit in the number system.

  • Students will know that a common scale factor links the corresponding sides of similar shapes but for congruent shapes the sides as well as the angles will be exact.
  • Students will know how to find the scale factor to calculate an unknown length of a similar shape and apply the conditions of congruency to identify congruent shapes.

Key Stage 4 Overview

The KS4 curriculum provides students with opportunities to build on their learning experiences gained during Key Stage 3.

The aims and objectives of the KS4 curriculum are to enable students to develop fluent knowledge, skills and understanding of mathematical methods and concepts; acquire, select and apply mathematical techniques to solve problems; reason mathematically, make deductions and inferences, and draw conclusions; and comprehend, interpret and communicate mathematical information in a variety of forms appropriate to the information and context.

Transferable skills enable young people to face the demands of further and higher education, as well as the demands of the workplace, and are important in the teaching and learning of our curriculum. Our curriculum aims to develop students’ cognitive skills (non-routine problem solving, expert thinking, metacognition, creativity), systems thinking (decision making and reasoning) and their critical thinking (cognitive skills such as analysing, synthesising and reasoning skills). At same time we seek to improve students’ interpersonal skills (active listening, oral communication, written communication, assertive communication and non-verbal communication) and their capacity for collaborative problem solving (teamwork, establishing and maintaining shared understanding, taking appropriate action, establishing and maintaining team organisation).

Read like a Mathematician

Mathematics has a language all of its own – not just its own vocabulary but the way sentences and maths questions are structured. Maths is clothed by polysemous vocabulary (words that have multiple meanings) that can foster ambiguity and unhelpful misconceptions, for example, prime, expression, converse, volume, mean, parallel, interest. Not only that, some maths words are homophones (words having the same pronunciation but different meanings, origins, or spellings) with more common words e.g. pi and pie, sine and sign, weight and wait, mode and mowed. Even simple mathematical operations, like subtraction, can be described in lots of ways in typical talk, such as ‘subtract’, ‘minus’, ‘difference’ or ‘take away’. Then you add in words like ‘decrease’, ‘reduce’ and ‘take off’. Teachers are constantly translating the language of maths. Teachers of maths will testify to the challenge of multi-step word problems. We can be confident then that reading in maths really does matter. Precision with mathematical talk will matter. Explicitly teaching on ‘how to read like a mathematician’ will prove beneficial for those students who are struggling with word problems. Reading matters in maths, more than students may assume.

Reading is built into the maths curriculum in several ways.

  • Guided reading tasks are incorporated into the start of each unit. Some of these provide background information linked to the upcoming unit of work; others provide information about history of maths, key figures and great moments; some show how maths links to the real world. Sharples guided reading strategies are used for these tasks, with a combination of teacher led and student led reading. The linked questions provide an opportunity for students to demonstrate that they have understood what they have read.
  • Students have regular exposure to worded and problem solving questions to develop students’ comprehension skills and support them in developing strategies to decode words and understand what the question is asking them to do.
  • Reading lists are shared in each pupil unit booklet – these include books linked to the topic being studied, as well as those that are more recreational.
  • Key words are shared within the pupil unit booklets and explicit vocabulary instruction is incorporated into lessons. Each unit includes a glossary of mathematical terms, along with accompanying diagrams and representations that may help.

Home learning

Learning beyond the classroom will involve a weekly homework set online for all students. All students have access to MyMaths, Mathswatch and Times Table Rock Stars to support their independent learning. Students should speak to their teacher if they have forgotten their login details. There is a weekly lunchtime support session for students in every year group where they can access help with homework tasks, complete their homework using a school computer, access revision support or additional consolidation of classwork.

 

Enrichment and other extracurricular activities

A wide range of Mathematics related enrichment options are available. Weekly clubs through the year including STEM, Maths in Art and Puzzle Club. Students have the opportunity to enter competitions including the UKMT individual and team challenges. There are also special events throughout the year, for example, national number days, STEM week and maths related trips.
