To do well on the foundation tier GCSE maths papers you need to practice and revise carefully. But, I hear you say “there’s so much to learn… where should I start?” Well, good question. Sometimes the daunting amount of content you need to learn can put people off starting GCSE maths revision all together. That’s’ why I’ve put together this list of the top 5 key topics you need to know for foundation tier GCSE maths. 

Practice the methods below and you’ll be well ahead of most other people taking the GCSE foundation maths papers.

Everyone should learn to be really confident working with fractions. That’s the best piece of advice I can give you. So many students are not comfortable with fractions. They try to convert everything to a decimal before doing calculations. Fractions, however, are much easier to work with than decimals, especially if you don’t have a calculator. 

You need to easily be able to:

  • add and subtract fractions; 
  • multiply and divide fractions;
  • work out a fraction of a whole number; and
  • convert between fractions, decimals and percentages. 

Luckily for you, we’ve got guides and worksheets for all of these key methods. You can find all of our guides on our learn online page


As with fractions, percentages are crucial for your GCSE maths exams, but also crucial for future life and work. Focus on understanding what percentages actually are and the different ways in which you can be asked to use them. 

You need to be confident with: 

  • finding a percentage of a number; 
  • finding one number as a percentage of another; and
  • compound interest and depreciation. 

The guides you need can be found here again. 

Solving Equations

Algebra is a key area you need to be strong on. This includes: equations, simultaneous equations, substitution, expanding brackets, factorising, quadratics, simplifying and formulae. Selecting one topic for this top 5 list is tough because they’re all really important. I’ve pushed myself though and had to go for solving equations. 

If you can learn the method I’ve set out in my solving equations guide, then you can do any linear equation they throw at you in the exam. The method for solving an equation is also really important to help your understanding of other areas of maths like trigonometry and Pythagoras’ theorem, where you need to quickly rearrange formulae. 

Angle Facts

Geometry and shape make up large parts of the GCSE maths course. There are quite a few rules to learn, but once you know them you’ll be fine.

Within this angle facts topic I’m including: 

  • angles in triangles and quadrilaterals; 
  • angles in a polygon; 
  • regular polygons; 
  • angles in parallel lines (corresponding, alternate and co-interior); and
  • bearings.

Area, Perimeter, Volume

Okay, so I have sort of condensed three topics into one here, but they’re all really important. 

Make sure you learn the rules for the area of these shapes: 

  • triangles; 
  • rectangles; 
  • trapeziums; 
  • parallelograms; 
  • compound shapes; and
  • circles. 

Make sure you learn the rules for the volume of these shapes: 

  • cuboids; 
  • cylinders; 
  • any prism; 
  • pyramids;
  • cones; and
  • spheres. 

So there you have it. The top 5 key topics you need to know for your GCSE Maths revision. Now get learning, practicing and revising! See how our online tutors can help or contact us if you have any questions or if you’d like help from one of our maths tutors.
