Year 8 Maths: What to Teach (England)

Your Teacher Information Pack for Year 8 Maths: every national curriculum statement, the tests and dates that matter, and trusted links. Tick what you're teaching and send it straight into the lesson plan maker.

The KS3 programme of study covers the whole key stage; it is not split by year.

Current. The government response to the Curriculum and Assessment Review (Nov 2025) says a revised national curriculum will be published by spring 2027 for first teaching from September 2028.

What to teach

Below is the official programme of study for Year 8 Maths: the statutory statements first, then any non-statutory notes and guidance, which schools don't have to follow.

Key stage 3 93 statutory statements

Through the mathematics content, pupils should be taught to:

• consolidate their numerical and mathematical capability from key stage 2 and extend their understanding of the number system and place value to include decimals, fractions, powers and roots
• select and use appropriate calculation strategies to solve increasingly complex problems
• use algebra to generalise the structure of arithmetic, including to formulate mathematical relationships
• substitute values in expressions, rearrange and simplify expressions, and solve equations
• move freely between different numerical, algebraic, graphical and diagrammatic representations [for example, equivalent fractions, fractions and decimals, and equations and graphs]
• develop algebraic and graphical fluency, including understanding linear and simple quadratic functions
• use language and properties precisely to analyse numbers, algebraic expressions, 2-D and 3-D shapes, probability and statistics

• 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 [for example, to a number of decimal places or significant figures]
