Importance of Mathematics key stage 3

Mathematical thinking is important for all members of a modern society as a habit of mind for its use in the workplace, business and finance; and for personal decision-making.  Mathematics is fundamental to national prosperity in providing tools for understanding science, engineering, technology and economics. It is essential in public decision-making and for participation in the knowledge economy.

Mathematics equips pupils with uniquely powerful ways to describe, analyse and change the world. It can stimulate moments of pleasure and wonder for all pupils when they solve a problem for the first time, discover a more elegant solution, or notice hidden connections. Pupils who are functional in mathematics and financially capable are able to think independently in applied and abstract ways, and can reason, solve problems and assess risk. 

Mathematics is a creative discipline. The language of mathematics is international. The subject transcends cultural boundaries and its importance is universally recognised. Mathematics has developed over time as a means of solving problems and also for its own sake.

Explanatory text

Study of mathematics: This is concerned with the learning processes for mathematics.

Applying suitable mathematics: This requires fluency and confidence in a range of mathematical techniques and processes that can be applied in a widening range of familiar and unfamiliar contexts, including managing money, assessing risk, problem-solving and decision-making.

Communicating mathematics: Pupils should be familiar with and confident about mathematical notation and conventions and be able to select the most appropriate way to communicate mathematics, both orally and in writing. They should also be able to understand and interpret mathematics presented in a range of forms.

Mathematical tools: Pupils should be familiar with a range of resources and tools, including graphic calculators, dynamic geometry and spreadsheets, which can be used to work on mathematics.

Mathematical methods: At the heart of mathematics are the concepts of equivalence, proportional thinking, algebraic structure, relationships, axiomatic systems, symbolic representation, proof, operations and their inverses.

Posing questions: This involves pupils adopting a questioning approach to mathematical activity, asking questions such as ‘How true?’ and ‘What if…?’

Mathematics is used as a tool: This includes using mathematics as a tool for making financial decisions in personal life and for solving problems in fields such as building, plumbing, engineering and geography. Current applications of mathematics in everyday life include internet security, weather forecasting, modelling changes in society and the environment, and managing risk (eg insurance, investments and pensions). Mathematics can be used as a way of perceiving the world, for example the symmetry in architecture and nature and the geometry of clothing.

Historical and cultural roots of mathematics: Mathematics has a rich and fascinating history and has been developed across the world to solve problems and for its own sake. Pupils should learn about problems from the past that led to the development of particular areas of mathematics, appreciate that pure mathematical findings sometimes precede practical applications, and understand that mathematics continues to develop and evolve.

Limitations and scope: Mathematics equips pupils with the tools to model and understand the world around them. This enables them to engage with complex issues, such as those involving financial capability or environmental dilemmas. For example, mathematical skills are needed to compare different methods of borrowing and paying back money, but the final decision may include other dimensions, such as comparing the merits of using a credit card that promotes a particular charity with one offering the lowest overall cost. The mathematical model or representation may have properties that are not relevant to the situation.

Key processes of Mathematics key stage 3

These are the essential skills and processes in mathematics that pupils need to learn to make progress.

2.1 Representing

Explanatory text

Processes in mathematics: The key processes in this section are clearly related to the different stages of problem-solving and the handling data cycle.

Representing: Representing a situation places it into the mathematical form that will enable it to be worked on. Pupils should begin to explore mathematical situations, identify the major mathematical features of a problem, try things out and experiment, and create representations that contain the major features of the situation.

Select mathematical information, methods and tools: This involves using systematic methods to explore a situation, beginning to identify ways in which it is possible to break a problem down into more manageable tasks, and identifying and using existing mathematical knowledge that might be needed. In statistical investigations it includes planning to minimise sources of bias when conducting experiments and surveys, and using a variety of methods for collecting primary and secondary data. ICT tools can be used for mathematical applications, including iteration and algorithms.

Make connections: For example, realising that an equation, a table of values and a line on a graph can all represent the same thing, or understanding that an intersection between two lines on a graph can represent the solution to a problem.

Generalisations: Pupils should recognise the range of factors that affect a generalisation.

Varying values: This involves changing values to explore a situation, including the use of ICT (eg to explore statistical situations with underlying random or systematic variation).

Different techniques: For example, working backwards and looking at simpler cases.

Analyse a situation: This includes using mathematical reasoning to explain and justify inferences when analysing data.

Reason inductively: This involves using particular examples to suggest a general statement.

Deduce: This involves using reasoned arguments to derive or draw a conclusion from something already known.

Calculating devices as appropriate: For example, when calculation without a calculator will take an inappropriate amount of time.

Record methods: This includes representing the results of analyses in various ways (eg tables, diagrams and symbolic representation).

Interpreting: This includes interpreting data and involves looking at the results of an analysis and deciding how the results relate to the original problem.

Evidence: This includes evidence gathered when using ICT to explore cases.

Patterns and exceptions: Pupils should recognise that random processes are unpredictable.

Someone else’s mathematical reasoning: Pupils should interpret information presented by the media and through advertising.

Communicating and reflecting: Pupils should communicate findings to others and reflect on different approaches.

Alternative solutions: These include solutions using ICT.

Range and content of Mathematics key stage 3

This section outlines the breadth of the subject on which teachers should draw when teaching the key concepts and key processes.

The study of mathematics should enable pupils to apply their knowledge, skills and understanding to relevant real-world situations.

Calculations and manipulations with rational numbers: This includes using mental and written methods to make sense of everyday situations such as temperature, altitude, financial statements and transactions.

Ratio and proportion: This includes percentages and applying concepts of ratio and proportion to contexts such as value for money, scales, plans and maps, cooking and statistical information (eg 9 out of 10 people prefer…).

Accuracy and rounding: This is particularly important when using calculators and computers.

Linear equations: This includes setting up equations, including inequalities and simultaneous equations. Pupils should be able to recognise equations with no solutions or an infinite number of solutions.

Polynomial graphs: This includes gradient properties of parallel and perpendicular lines.

Sequences and functions: This includes a range of sequences and functions based on simple rules and relationships.

2D and 3D shapes: These include circles and shapes made from cuboids.

Scale: This includes making sense of plans, diagrams and construction kits.

Compound measures: This includes making sense of information involving compound measures, for example fuel consumption, speed and acceleration.

Surface areas and volumes: This includes 3D shapes based on prisms.

The handling data cycle: This is closely linked to the mathematical key processes and consists of:

• specifying the problem and planning (representing)

• collecting data (representing and analysing)

• processing and presenting the data (analysing)

• interpreting and discussing the results (interpreting and evaluating).

Presentation and analysis: This includes the use of ICT.

Spread: For example, the range and inter-quartile range.

Probabilities: This includes applying ideas of probability and risk to gambling, safety issues, and simulations using ICT to represent a probability experiment, such as rolling two dice and adding the scores.

Curriculum opportunities of Mathematics key stage 3

During the key stage students should be offered the following opportunities that are integral to their learning and enhance their engagement with the concepts, processes and content of the subject.

The curriculum should provide opportunities for pupils to:

  1. develop confidence in an increasing range of methods and techniques

  2. work on sequences of tasks that involve using the same mathematics in increasingly difficult or unfamiliar contexts, or increasingly demanding mathematics in similar contexts

  3. work on open and closed tasks in a variety of real and abstract contexts that allow them to select the mathematics to use

  4. work on problems that arise in other subjects and in contexts beyond the school

  5. work on tasks that bring together different aspects of concepts, processes and mathematical content

  6. work collaboratively as well as independently in a range of contexts

  7. become familiar with a range of resources, including ICT, so that they can select appropriately.

Explanatory text

Other subjects: For example, representing and analysing data in geography, using formulas and relationships in science, understanding number structure and currency exchange in modern foreign languages, measuring and making accurate constructions in design and technology, and managing money in economic wellbeing and financial capability.

Contexts beyond the school: For example, conducting a survey into consumer habits, planning a holiday budget, designing a product, and measuring for home improvements. Mathematical skills contribute to financial capability and to other aspects of preparation for adult life.

Work collaboratively: This includes talking about mathematics, evaluating their own and others’ work and responding constructively, problem-solving in pairs or small groups, and presenting ideas to a wider group.

Become familiar with a range of resources: This includes using practical resources and ICT, such as spreadsheets, dynamic geometry, graphing software and calculators, to develop mathematical ideas.
