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
