Objectives:


Support:

  • Use letter symbols to represent unknown numbers or variables; know the meanings of the words term, expression and equation.
  • Construct and solve simple linear equations with integer coefficients (unknown on one side only) using an appropriate method (e.g. inverse operations).

Core:

  • Begin to distinguish the different roles played by letter symbols in equations, formulae and functions; know the meanings of the words formula and function.
  • Construct and solve linear equations with integer coefficients (unknown on either or both sides, without and with brackets) using appropriate methods (e.g. inverse operations, transforming both sides in the same way).
  • Use formulae from mathematics and other subjects; substitute integers into simple formulae, including examples that lead to an equation to solve; derive simple formulae.

Extension:

  • Construct and solve linear equations with integer coefficients (with and without brackets, negative signs anywhere in the equation, positive or negative solution), using an appropriate method.
  • Use formulae from mathematics and other subjects; substitute numbers into expressions and formulae; derive a formula and, in simple cases, change its subject.

Key Vocabulary:

  • algebraic expression, formula, function, partition, multiply out, cubed, to the power of, variable, evaluate, construct, solve, collect like terms.
