Instructor: Okay. So what we’re going to do today is we’re going to practice some estimation around getting answers. I’m going to give you a problem, and what I want you to be able to tell me is an answer that’s too big, and an answer that’s too small. Then I’m going to ask you why those answers are too big and too small. So I want a wrong answer in two ways. 

Student 1: One hour.

Instructor: One hour. Why is that too small?

Student 1: Because he won’t even earn anything. He’ll be broke.

Instructor: Perfect.

Student 1: Wait. Oh yeah, he’ll be broke.

Instructor: Why will he be broke?

Student 1: He won’t be able to add up money because he’s just spending a lot of money and he’s not making a lot of money.

Instructor: Perfect. Anyone else have an answer they know is too small?

Student 2: 5 hours?

Instructor: Why?

Student 2: Well, he has to reach $308, so I’m guessing he has to take at least 30 hours or whatever, so anything below $20 or $15 is too small, in my opinion.

Instructor: Okay. What answer do you think is too big, like a big answer?

Student 3: 200 hours.

Instructor: Okay. 200 hours. Why would that be too big?

Student 3: Because I feel like that would just go really overboard. Even if he worked for that exact money per hour and even with the monthly spendings, it would just be way too much.

Instructor: Now I would like for you to give me an answer that is just about right, and tell me why you think it’s just about right.

Student 4: Like 30.

Instructor: Okay. Why do you think 30?

Student 4: Because he would just be spending too much and not earning the amount he wants.

Student 2: Well, I wish I had a calculator here, but if I do 10 times what…

Instructor: You can talk about it.

Student 2: I’m looking at 10 times 30

Student 1: Lets do 11 times, so we can round it up.

Student 2: Okay. Times 30, and that would be like around the 300-ish mark. 

Student 3: Minus 17 per month.

Student 2: Yeah.
