One-Step Inequalities and Number Lines for 6th Grade
By Alexandrea B.
A practice set for 6th graders that walks through solving one-step inequalities and graphing their solutions on number lines, with a reference section on inequality symbols, open and closed circles, and the flip rule for negative multiplication and division. It builds equation-solving fluency and the ability to represent solution sets visually.

Teacher Guide & Tips
- Use as a 45-minute lesson-closing or homework set after students have solved one-step equations, starting with the reference box as a quick review of symbols and circles.
- Discussion question: Why does the sign flip when we divide by a negative number, but not when we add or subtract? Have students test it with a simple true statement like 2 < 5 before generalizing.
- Scaffold for struggling readers: have them say each symbol aloud as a full phrase ("x is less than or equal to 4") and mark open versus closed circles on a blank number line before graphing.
- Extension for advanced students: ask them to write a real-world inequality (such as a budget or speed limit) and explain which circle type and direction their graph should use.
- Estimated time: about 25 to 30 minutes for the practice problems, plus 10 minutes for review of the reference section.
