Step 8 Objective

Transform algebraic expressions by factorising to produce a single term multiplied by terms in a bracket.

Examples of what pupils should know and be able to do

Factorise 6a + 10 = 2(3a + 5).

Probing questions

How can you check that your factorising is correct? (Look for grid multiplication to demonstrate that the expressions are equivalent.)

What if pupils find this a barrier?

Refer to Step 6 multiply a single term over a bracket, and reinforce the connections between the grid method for multiplying and how the grid can be used to work out how to factorise an expression.
