Absolute Value Inequalities Practice Set for Grade 9
A practice set of roughly a few pages that walks 9th graders through solving absolute value inequalities, contrasting the 'less than' (AND) and 'greater than' (OR) cases with number-line visuals and symbolic rewriting. It builds skills in translating distance statements into compound inequalities and interpreting solution sets on a number line, and it works well as a guided practice block in an Algebra I or Algebra II unit.

Teacher Guide & Tips
- Use this as a 40-50 minute guided practice block after introducing absolute value as distance from zero, letting students work the 'less than' examples first before moving to 'greater than.'
- Discussion question: Why does |x| < 3 lead to an AND compound inequality while |x| > 3 leads to an OR, and how can the number line explain the difference?
- Scaffold for struggling readers: Have them sketch the number line for each problem before writing any algebra, and rewrite |x| < a as -a < x < a in their own words.
- Extension for advanced students: Ask them to create their own absolute value inequality with no solution or all real numbers as the solution, and justify why it behaves that way.
- Estimated time: about 45 minutes for the full set, including a brief whole-class debrief on the AND versus OR distinction.
