*Students will investigate the history of Pi Day and create a game to celebrate this mathematical holiday.*

### PROCESS:

- Have students conduct research to learn how people around the world celebrate Pi Day. Encourage them to search for both instructional activities that students can do in the classroom and fun, interactive events that involve a larger audience.
- Rejoin as a class. Invite students to share what they learned. Guide the class to recognize that while Pi Day is based on a mathematical principle, the spirit of the day is fairly light-hearted.
- Instruct students to design a game for a Pi Day celebration. The game can be based on an existing idea or it can be something they imagined on their own.
- Have students present their games to the class.

### ASSESSMENT:

After all games are completed, invite classmates to share their opinions. How was each game connected to pi? Did each game have the light-hearted approach celebrated on Pi Day?

### CUSTOMIZE THE LESSON:

**Grades 3-4:**

Investigate the history of Pi Day as a class. Then divide the class into small groups. Instruct each group to create a game related to Pi Day. The only supplies they are allowed to use are pencils, paper and glue.

**Grades 5-6:**

Divide the class into small groups. Have groups investigate the history of Pi Day. Then instruct each group to create a game related to Pi Day. The game board must be shaped like a pie.

**Grades 7-8:**

Divide the class into small groups. Have groups investigate the history of Pi Day. Then instruct each group to create a game related to Pi Day. The game board must be shaped like the symbol for pi.

**Grades 9-10:**

Assign each student a partner. Have pairs investigate the history of Pi Day. Then instruct each pair to create a game related to Pi Day. The game board must be shaped like the symbol for pi, the playing pieces must be shaped like a piece of pie and the game must involve math.
