This lesson accompanies the BrainPOP topic **Pi****,** and supports the standard of using the formulas for the area and circumference of a circle to solve problems. Students demonstrate understanding through a variety of projects.

**Step 1: ACTIVATE PRIOR KNOWLEDGE**

Display this still from the movie (timestamp: 1:04):

Explain that this is the symbol for pi, which has an approximate value of 3.14. Ask students:

*Where have you seen pi before?**What do you think it might be used for?**Why might mathematicians use a symbol to represent pi?*

**Step 2: BUILD KNOWLEDGE**

- Read the description on the
**Pi topic page**. - Play the
**Movie**, pausing to check for understanding. - Assign
**Related Reading.**Have students read one of the following articles: “Dates and Times” or “Laws and Customs.” Partner them with someone who read a different article to share what they learned with each other.

**Step 3: APPLY and ASSESS**

Assign the **Pi 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 pi 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 an instructional video for employees at a bakery that answers this question:*How do you determine the area and circumference of the pies, cakes, and cookies to ensure they’re the correct sizes?***Make-a-Map**: Make a concept map identifying and describing features and uses of pi.**Creative Coding**: Code a math problem challenging others to find the circumference and area of a circle.**Primary Source****Activity**: Analyze a bill proposed by an amateur mathematician that would have established an incorrect value for pi. Cite evidence to answer accompanying questions.
