Year 8 Maths

Overview

Term 

What are we learning 

 

1 

Powers and Roots 

Prime Factorisation 

Rounding 

Fractions 

Negative Number Review 

  • Use integer powers and associated real roots (square, cube and higher), recognise powers of 2, 3, 4, 5, 10 and distinguish between exact representations of roots and their decimal approximations. 
  • Use the concepts and vocabulary of prime numbers, factors (or divisors), common factors, prime factorisation, including using product notation and the unique factorisation property. 
  • Round numbers and measures to an appropriate degree of accuracy [for example, to a number of decimal places or significant figures]. 
  • Multiply and divide fractions and mixed numbers. 
  • Negative Number Manipulation. 

2 

Linear Equations 

Coordinates and Basic Graphs 

  • Use algebraic methods to solve linear equations in one variable (including all forms that require rearrangement). 
  • Model situations or procedures by translating them into algebraic expressions or formulae and by using graphs. 

3 

Units of Measurement 

Angles 

Circumference 

  • Use standard units of mass, length, time, money and other measures, including with decimal quantities. 
  • Understand and use the relationship between parallel lines and alternate and corresponding angles. 
  • Calculate interior and exterior angles of (regular) polygons. 
  • Calculate and solve problems involving perimeters of 2-D shapes (including circles) and composite shapes. 

4 

Proportional Reasoning 

Fractions, Decimals and Percentages 

Ratio 

  • Understand that a multiplicative relationship between two quantities can be expressed as a ratio or a fraction. 
  • Solve problems involving percentage change, including: percentage increase, decrease and original value problems and simple interest in financial mathematics. 
  • Divide a given quantity into two parts in a given part:part or part:whole ratio; express the division of a quantity into two parts as a ratio. 

5 

Area of Composite Shapes 

Presenting and Interpreting Data 

Averages 

  • Derive and apply formulae to calculate and solve problems involving area of triangles, parallelograms, trapezia and (part)circles. 
  • Construct and interpret appropriate tables, charts, and diagrams, including frequency tables, bar charts, pie charts and vertical line (or bar) charts for ungrouped and grouped numerical data. 
  • Describe, interpret and compare observed distributions of a single variable through appropriate measures of central tendency (mean, mode, median) and spread (range, consideration of outliers). 

6 

3-D Visualisation 

Volume 

  • Use the properties of faces, surfaces, edges and vertices of cubes, cuboids, prisms, cylinders, pyramids, cones and spheres to solve problems in 3-D. 
  • Derive and apply formulae to calculate and solve problems involving volume of cuboids (including cubes) and other prisms (including cylinders).
