What is it?
Students typically start expanding and factorising brackets in Year 7, and continue to do so all the way up to GCSE. Finding unique ways in which to practice this essential skill year-on-year can be tricky. Luckily, this variation on the traditional worksheet provides an engaging way to recap familiar methods with a twist!
To complete the task, learners must work backwards from the given answers in order to fill in the blanks. Over the 18-question exercise they demonstrate a number of skills, including expanding, factorising and simplifying algebraic expressions.
How can it be used?
This format works best when used to consolidate existing knowledge, rather than to teach the basics. Build confidence among your students by starting with a few worked examples together before letting them tackle the problems independently.
Encourage learners to self-check for inaccuracies by covering up the answers and working through completed questions. This ensures that they learn from any mistakes and, equally importantly, allows you to determine whether or not they have fully understood the concept.
