**Brief Description:**  Students will learn about prime and composite numbers and their factors.

**Know Before You Start:** This lesson is a great introduction to **prime** and **composite numbers**. Pairs of dice will be needed.

**Hook:**

- Read and discuss the sample comic.
  
    - What’s the difference between a prime and composite number?
    - Is Maggie correct about the buses? 
- Practice finding the factors of prime and composite numbers as a class.
- Have students work in pairs, taking turns providing numbers for their partner to determine if it is a prime or composite number and provide the factors. 

**Activity:**

- Give each student a pair of dice.
- Have students roll the dice to create a two digit number (one number from each die.)
- Students will now create a four-panel comic 
    - In **Panel 1:** Have students explain the difference between prime and composite numbers by providing a definition/explanation in their own words.
    - In each of the following panels, students will share the number they rolled, determine if it is a prime or composite number and provide the factors.
    - Students will repeat this process for three separate numbers.

**Closure:**

- Have students share their comic with a partner.

**Differentiation:**

- Allow students to use the speech-to-text feature.
- Allow students to use the voiceover feature to read their comics aloud.
- Provide the definitions of prime and composite numbers for students. 
- Provide a prime and composite number chart. 
- Provide sentence stem: "*____ is a prime/composite number because _______."*
- Allow students to work in pairs.
