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.

Maths

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

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?

How do you write $$7\times a$$ using correct algebraic notation?

Which of these show a correctly written identity?

Match the expressions to their simplified form.

Which of the below simplifies to $$a^3b$$?

This lesson will soon be taken down.
