Letters as variables. Expressions, equations, formulae, and identities. Sequences. Simple linear graphs. The discipline of generalising from particular cases.

NC outcomes (paraphrased)

Pupils should be taught to:

  • Use and interpret algebraic notation (multiplication, brackets, indices)
  • Substitute numerical values into formulae and expressions
  • Understand and use the concepts of expressions, equations, formulae, identities
  • Simplify and manipulate algebraic expressions
  • Solve linear equations in one variable
  • Work with sequences (linear, including the nth term)
  • Plot graphs of linear functions; recognise and interpret graphs
