*Click to open and customize your own copy of the **Pi Lesson Plan. **

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 BACKGROUND**

- Read the description on the
**Pi topic page**. - Play the
**Movie**, pausing to check for understanding.

Have students read one of the following **Related Reading** 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: ENGAGE**

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 explaining how to determine the area and circumference of the pies, cakes, and cookies to ensure they’re the correct sizes.**(Essential Literacy Skill: Determine central ideas)****Make-a-Map**: Make a concept map identifying and describing features and uses of pi.**(Essential****Literacy Skill: Acquire and use domain specific words and phrases.)****Creative Coding**: Code a math problem challenging others to find the circumference and area of a circle.**(Essential Literacy Skill: Integrate content presented in diverse formats)****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.**(Essential Literacy Skill:Cite specific evidence to support conclusions drawn)**

**Step 4: APPLY & ASSESS **

**Apply**: Students complete the **Pi Worksheet**, applying essential literacy skills while demonstrating what they learned about this topic.

**Assess: **Wrap up the lesson with the **Pi Quiz**.

**Step 5: EXTEND LEARNING**

**Related BrainPOP Topics**: Deepen understanding of pi with these topics: **Circles** and **Rational and Irrational Numbers**.
