Transcript: Harry the Substitute Teacher

HARRY: Today's my first day working as a substitute teacher. I'm a little nervous. What if the kids go wild? I won't know how to handle them! Noooooo!!!

PRINCIPAL: You're fired.

HARRY: Good morning, class. I'm name…name…my name is Mr. Wilson.

STUDENT #1: It's a pleasure to meet you.

HARRY: Why, thank you.

STUDENT #2: Can you tell us a little about yourself?

HARRY: Well, um, I can ride a unicycle.

STUDENTS: Wow…

HARRY: And I can juggle.

STUDENTS: Cool!

STUDENT #3: Show us!

STUDENTS: Yeah, show us!

HARRY: Okay. We need to make some room. Now we need to set up the room so you can take a quiz. Please arrange the desks in rows that have equal numbers of desks in each row. Okay. What's a possibility for arranging these 24 desks?

STUDENT #4: One row of 24.

HARRY: Let's do that. How many people think this is a good way to arrange the desks? Well, what's another possibility?

STUDENT #6: Two rows of twelve.

HARRY: Show me.

HARRY: What do you think?

STUDENTS: No good.

HARRY: Another way?

STUDENT #7: Three rows of eight desks.

HARRY: Let's try it.

STUDENT #8: We should try five desks in each row.

HARRY: Go ahead.

STUDENT #9: This doesn't work.

HARRY: Why?

STUDENT #9: Because one row has only four desks in it.

STUDENT #10: That's because you can't multiply five by a whole number to get 24.

STUDENT #11: The other numbers are factors of 24 and five isn't.

HARRY: You're right! So is there another possibility that'll work?

STUDENT #12: Four rows of six desks.

HARRY: Let's try that.

HARRY: Are there any other factors?

STUDENTS: No.

HARRY: Great! Now, it's time for the quiz.

STUDENTS: Awww...

HARRY: Take one and pass it back. For the quiz, write down the factors of 24.
