A factor is a term which exactly divides another term.

The highest common factor of two or more terms which can be divided by all other possible common factors.

HCF is an abbreviation for highest common factor.

Factorise means to express a term as the product of its factors.

In this unit, pupils formalise algebraic notation and terms and begin to formulate an understanding of basic algebraic manipulation. This understanding is built upon in the future unit where pupils learn how to solve linear equations

In this unit, pupils learnt how to represent the structure of a problem with two unknowns using a diagram. This understanding is built upon in this unit and formalised

In this unit, pupils learn about generalisation and formal algebraic manipulation techniques such as substitution, collecting like terms and factorising.
