Learning Objective

Students will interpret, write, and graph linear inequalities in one variable, connecting symbolic notation to number line representations and real-world sports constraints.

Lesson Overview

Students progress from reading and writing simple inequalities to graphing compound inequalities on number lines, using sports contexts throughout. Each task changes exactly one variable to build fluency and conceptual depth.

Materials

  • Vertical whiteboards or large paper
  • Dry-erase markers and erasers
  • Pencils and notebook paper
