Big Ideas:
- Inequalities represent more than one value.
- Inequalities can be shown using number lines.
This lesson builds on the understanding that inequalities have more than one solution by asking students to develop a visual model that shows all of those solutions. In this task, students are given a real-life situation that can be represented as an inequality. Students are then asked to generate their own visual model that represents the inequality. In the task review, students are given number lines as examples of ways to represent all solutions to an inequality. This concept builds toward solving for variables in inequalities and graphing their solutions.
