Understand and use the relationships between the four operations, and the principles (not the names) of the arithmetic laws.

Use brackets.

Core:

Use letter symbols to represent unknown numbers or variables; know the meanings of the words term, expression and equation.

Understand that algebraic operations follow the same conventions and order as arithmetic operations.

Simplify linear algebraic expressions by collecting like terms; begin to multiply a single term over a bracket (integer coefficients).

Use simple formulae from mathematics and other subjects, substitute positive integers into simple linear expressions and formulae and, in simple cases, derive a formula.

Identify the necessary information to solve a problem; represent problems mathematically, making correct use of symbols, words, diagrams and tables.

Extension:

Begin to distinguish the different roles played by letter symbols in equations, formulae and functions; know the meanings of the words formula and function.

Know that algebraic operations follow the same conventions and order as arithmetic operations; use index notation for small positive integer powers.

Simplify or transform linear expressions by collecting like terms; multiply a single term over a bracket.

Substitute integers into simple formulae, including examples that lead to an equation to solve, and positive integers into expressions involving small powers (e.g. 3x2 + 4 or 2x3).
