Worksheet to introduce and practise solving quadratic inequalities

Worksheet to introduce and practise solving quadratic inequalities

This 4-page worksheet introduces the method for solving quadratic inequalities of the form x^2k. After explaining the method there is a short exercise to practise solving inequalities of the form x^2k. There are then some examples that require simplification or rearranging to solve (e.g. 3x^2-75>0) to work through as a class, followed by an exercise of similar questions for students to attempt. All answers are included.

Set of resources to cover the whole topic of inequalities on graphs

Set of resources to cover the whole topic of inequalities on graphs

This set of resources contains everything you need to teach the topic of inequalities on graphs. The students need to be confident with straight line graphs for this topic so the first worksheet is a refresher of those. Next is a powerpoint with worked examples of finding the single inequality represented by a shaded region. The worksheet that follows practises finding the single inequality that describes the given shaded region (4 pages). The next worksheet practises finding the 3 inequalities that describe the given shaded region (4 pages). The worksheet "Inequalities on graphs" gives students lots of practice drawing the shaded region (both single and multiple inequalities) and finding inequalities for shaded regions (10 pages). The final resource is intended as a homework or summative assessment (4 pages). All answers are included for printing/projecting for your class to check their answers.

Clumsy Clive Number and Algebra Bundle

Clumsy Clive Number and Algebra Bundle

These are all available for free individually but if you don't have the time then this is for you. Clive makes common mistakes, mistakes you'll have seen in class. Your students need to find the mistakes, correct them and explain where Clive has gone wrong so that he doesn't do the same thing again. These activities are designed to create discussion in class and can be used to assess understanding.
