Maths Key Stage 3 Overview

In Maths key stage 3 your child will have left primary school and will now be in secondary school. Maths  key stage 3 doesn’t introduce your child to fundamentally new concepts. Instead they are taught to consolidate their learning and learn known concepts and mathematical rules more in depth. Maths key stage 3 places children in either year 7, 8 or 9. The work in these years will be leading up to their GCSE’s in year 11.

 

Algebra

Your child should learn to:

  • Use and interpret algebraic symbols.
  • Be able to use scientific formulae.
  • Simplify and manipulate algebraic expressions.
  • Collect ike terms.
  • Multiplying a single term over a bracket.
  • Taking out common factors.
  • Understand and use standard mathematical formulae.
  • Use algebraic methods to solve linear equations.
  • Work with coordinates.
  • Recognise, sketch and product graphs of liner and quadratic functions of one variable.

 

Number

Your  child will learn to:

  • Understand and use place value for decimals, measures and integers of any size.
  • Use the four operations including formal written methods with positive and negative numbers.
  • Understand the priority of operations, including brackets, powers, roots and reciprocals.
  • Recognise and use relationships between operations including inverse operations.
  • Define percentage as ‘number of parts per hundred’.
  • Use standard units of mass, length, time, money and other measures including with decimal quantities.
  • Round numbers and measures to an appropriate degree of accuracy.
  • Use a calculator and other technologies to calculate results accurately and then interpret them appropriately.

 

Shape

Your child will learn to:

  • Formulae to calculate and solve problems involving perimeter and area of triangles, parallelograms, trapezia, and other prisms.
  • Calculate and solve problems involving: perimeter of 2D shapes.
  • Draw and measure line segments and angles in geometric figures.
  • Use the standard ruler and compass constructions.
  • Describe, sketch and draw using conventional terms and notations: points, lines, parallel lines, perpendicular lines, right angles, regular polygons and other polygons.
  • Label and illustrate triangles properly.
  • Identify properties of translations, rotations and reflections.
