ALGEBRAIC TECHNIQUES

OVERVIEW

Building on understanding of equivalence from Year 7, students will learn how to expand over a single bracket and factorise. All students will revisit and extend their knowledge of how to solve linear equations, now to include brackets and the unknown on both sides. Students will also understand how to solve formal inequalities for the first time, learning the meaning of a solution set.

Following this learners will look at sequences with more complex algebraic rules now that students are familiar with a wider range of notation.

Lastly learners will explore the ideas behind the addition and subtraction laws of indices which will be revisited when standard form is revisited when standard form is studied next term.
