Support (from Y7 teaching programme) • Use letter symbols to represent unknown numbers or variables; know the meanings of the words term , expression and equation . • Simplify linear algebraic expressions by collecting like terms
Core (from Y8 teaching programme) • 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
Extension (from Y9 teaching programme) • Use index notation for integer powers and simple instances of the index laws (e.g. multiply out x(x+2)) • Simplify or transform algebraic expressions by taking out single term common factors
