Unitising means treating groups that contain, or represent, the same numbers of things as ‘ones’ or ‘units’.

Like terms are terms that have the same set of variables and corresponding exponents.

Problem solving with expressions and equations

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.

Expressions and equations

$$3a, 10a, {{1} \over {3}}a, 0.5a,$$ and $$a$$ are all examples of what in algebra?

$$5x$$ and $$5x^2$$ are not like terms because the variables do not have corresponding {{}}.

In the expression $$x^2+7x+10$$ the $$x^2$$, the $$7x$$ and the $$10$$ are all known as what?
