These are two amazing worksheets that really help students learn the concepts and teachers teach the concepts. The first worksheet is a single sided and covers graphing Absolute Value Inequalities. The second worksheet is a double sided and covers Special functions: Absolute Value, Piecewise and Step Functions. There is an answer key for both pages. The problems flow from easy to hard, and covers the different shifts. This is all you need for Special Functions. My whole department uses these worksheets. Please, check out my other worksheets.
