Introduction
(5 minutes)- Distribute the vocabulary card for the word area and ask students to label the sides based on the equation on the card.
- Let them turn and show their answers to their elbow partners.
- Ask for a volunteer to explain how they labeled the sides. Rephrase their explanation using key vocabulary terms (i.e., "width," "length," "square units," etc.).
- Have a student read the student-friendly language objective: "I can explain how to use the area formula with key vocabulary and visuals."
