Pupils should be taught to understand and use standard mathematical formulae; rearrange formulae to change the subject

Here are some specific activities, investigations or visual aids we have picked out. Click anywhere in the grey area to access the resource.

Changing The Subject Video Otherwise known as rearranging the formula, this video shows how to change the subject of an equation.

Changing The Subject Rearrange a formula in order to find a new subject in this self marking exercise.

Formulae to Remember The traditional pairs or pelmanism game adapted to test recognition for formulae required to be memorised for GCSE exams.

Here are some exam-style questions on this statement:

Algebra Pupils begin their study of algebra by investigating number patterns. Later they construct and express in symbolic form and use simple formulae involving one or many operations. They use brackets, indices and other constructs to apply algebra to real word problems. This leads to using algebra as an invaluable tool for solving problems, modelling situations and investigating ideas. If this topic were split into four sub topics they might be: Creating and simplifying expressions; Expanding and factorising expressions; Substituting and using formulae; Solving equations and real life problems; This is a powerful topic and has strong links to other branches of mathematics such as number, geometry and statistics. See also "Number Patterns", "Negative Numbers" and "Simultaneous Equations".
