Mathematics

Key Stage 3

The national curriculum for Mathematics aims to ensure that all students:

  • Become fluent in the fundamentals of Mathematics, including through varied and frequent practice with increasingly complex problems over time, so that students 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.

At KS3 decisions about progression are based on the security of students’ understanding and their readiness to progress to the next stage. Students who grasp concepts rapidly are challenged by further rich and sophisticated problems before any acceleration through new content in preparation for key stage 4. Those who are not sufficiently fluent are encouraged to consolidate their understanding, through additional practice, before moving on.

Year 9

Algebra

Pupils will develop further their understanding of sequence, algebraic manipulation including use of brackets and factorising. This will develop their skills from year 7 by introducing extended use on indices. They will explore the graphs of linear functions with an increasing degree of sophistication. Pupils will also learn how to create tables of values for quadratic and cubic functions and plot their graphs.

They will further extend their understanding of forming and solving equations. Use and represent inequalities and solve quadratic and cubic equations using a systematic trial and improvement method.

Data Handling

 Pupils will also explore how they can calculate an estimate for the mean, and locate the class interval where the mode and median lie from grouped data. Throughout the unit pupils will be encouraged to think about comparing two sets of data using the techniques outlined. They will develop their understanding of scatter graphs and how pairs of scatter graphs can be used to compare strength of correlation.

They continue to develop the concepts of theoretical and experimental probability

Shape and Measure

In this unit they will explore and extend methods for finding the area and volume of shapes. Pupils will spend most of their time investigating circles and prisms and applying methods and formulas to problems.

They will continue to develop their knowledge and understanding of the angle and other associated geometric properties of shapes. They focus on transformations on coordinate axes and how shapes and their properties change under single and combined transformations.

Numbers

Extensive work is carried out on multiplying and dividing decimal numbers by powers of 10. They will continue to learn how to compare and order decimal numbers and negative numbers in context and consolidate efficient written methods for adding and subtracting whole numbers and decimals with up to 2 places. Decimals and percentages are revisited.

There will be a greater emphasis on mathematical reasoning, communication and problem solving skills.

The content is divided in to six main areas:
1.    Number
2.    Algebra
3.    Ratio, proportion and rates of change
4.    Geometry and measures
5.    Probability
6.    Statistics
