Year 8 are on the angles topic and about to move onto the topic of algebra including formula and sequences.

Week beginning

Year 8 objectives covered

Useful activities/links


  • understand and use alternate and corresponding angles on parallel lines
  • derive and use the sum of angles in a triangle (e.g. to deduce and use the angle sum in any polygon, and to derive properties of regular polygons)



Extension topics

  • make links to similarity (including trigonometric ratios) and scale factors
  • know the exact values of sinθ and cosθ for θ = 0°, 30°, 45°, 60° and 90°; know the exact value of tanθ for θ = 0°, 30°, 45° and 60°
  • know the trigonometric ratios, sinθ = opposite/hypotenuse, cosθ = adjacent/hypotenuse, tanθ = opposite/adjacent

apply it to find angles and lengths in right-angled triangles in two dimensional figures 

Angles: polygons 


Trigonometry introduction

Trigonometry missing sides:

Trigonometry missing angles: 


  • substitute numerical values into scientific formulae
  • rearrange formulae to change the subject 

Algebra: changing the subject 



  • generate terms of a sequence from either a term-to-term or a position-to-term rule

deduce expressions to calculate the nth term of linear sequences





Extension topics


recognise and use Fibonacci type sequences, quadratic sequences

  • deduce expressions to calculate the nth term of quadratic sequences

recognise and use simple geometric progressions (r^n where n is an integer, and r is a rational number > 0 )  

Sequences: patterns

Sequences: nth term 

Quadratic nth term – Version 1
