This lesson accompanies the BrainPOP topic Graphing and Solving Inequalities, and supports the standard of writing an inequality to represent a constraint or condition in a real-world or mathematical problem. Students demonstrate understanding through a variety of projects.
Step 1: ACTIVATE PRIOR KNOWLEDGE
Display an inequality, like this one from the movie (timestamp: 1:22):
Ask students:
- How does this inequality resemble an equation? How does it differ?
- How might you use what you know about solving for a variable in an equation to solve for x in this inequality?
Step 2: BUILD KNOWLEDGE
- Read the description on the Graphing and Solving Inequalities topic page.
- Play the Movie, pausing to check for understanding.
- Assign Related Reading and have students read the article “In Practice.” Prompt students to discuss what they learned with one other.
Step 3: APPLY and ASSESS
Assign Graphing and Solving Inequalities Quiz, prompting students to apply essential literacy skills while demonstrating what they learned about this topic.
Step 4: DEEPEN and EXTEND
Students express what they learned about graphing and solving inequalities while practicing essential literacy skills with one or more of the following activities. Differentiate by assigning ones that meet individual student needs.
- Make-a-Movie: Produce a tutorial that explains how to solve for x and graph 5x + 4 < 29.
- Make-a-Map: Create a concept map identifying the steps to find x in the inequality 4x – 3 < 17.
- Creative Coding: Code a math problem involving graphing an inequality and challenge a classmate to solve it.
