This lesson accompanies the BrainPOP topic 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:

8 > x > 2

• How might you read this expression?
• What number could x be?

Step 2: BUILD KNOWLEDGE

• Read the description on the Inequalities topic page.
• Play the Movie, pausing to check for understanding.
• Have students read the Related Reading article “Plus/Minus.” Prompt students to discuss what they learned with one other.

Step 3: APPLY and ASSESS

Students take the Inequalities Quiz, applying essential literacy skills while demonstrating what they learned about this topic.

Step 4: DEEPEN and EXTEND

Students express what they learned about 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 movie explaining how to represent a real-world situation with an inequality.
• Make-a-Map: Create a concept map identifying all of the possible values for x in the inequality 0 < x < 6.
• Creative Coding: Code a math problem involving an inequality and challenge a classmate to solve it.
