This lesson accompanies the BrainPOP topic Pythagorean Theorem, and supports the standard of applying the Pythagorean Theorem to determine unknown side lengths in right triangles. Students demonstrate understanding through a variety of projects.

Step 1: ACTIVATE PRIOR KNOWLEDGE

Display an image of a right triangle, like this one from the movie (timestamp: 0:50): Prompt students to share what they notice about the triangle, including its angles and side lengths.

Step 2: BUILD KNOWLEDGE

• Read the description on the Pythagorean Theorem topic page.
• Play the Movie, pausing to check for understanding.
• Assign Related Reading. Have students read one of these two articles: “Way Back When” or “Real Life.” Partner them with someone who read a different article to share what they learned with each other.

Step 3: APPLY and ASSESS

Assign the Pythagorean Theorem 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 the ​​Pythagorean Theorem 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 uses an example to prove the Pythagorean theorem.
• Make-a-Map: Create a concept map identifying the steps to finding the length of a leg of a right triangle when given the length of its other leg and hypotenuse.
• Creative Coding: Code a math problem involving the Pythagorean Theorem, and challenge a classmate to solve.
