Instructor: Now, I'm going to pour some juice in here. And you watch me pour. OK. And now, I'm going to pour the same amount of juice in here. OK. Are they the same?

Matee: Yes.

Instructor: About the same? So if this was your juice—

Matee: This is a bigger amount than this.

Instructor: Is it? Let's compare them. You're right. We need some more in here. Thank you very much. Are they the same now?

Matee: A little bit.

Instructor: A little bit more. OK.

Matee: They're the same now.

Instructor: Good. Thank you. Thank you very much. OK. Now Matee, let's pretend that this is your juice. This is my juice. Do we have the same amount of juice to drink? If I drank my juice and you drank your juice—

Matee: —This

Instructor: —would we

Matee: —has more.

Instructor: Let's just see. I don't know, they look the same to me.

Matee: That's right.

Instructor: Huh?

Matee: That's right.

Instructor: Yeah. They're the same, aren't they? So if you drank your juice and I drank my juice, would we have the same amount of juice to drink?

Matee: Yes.

Instructor: OK. Good. Now, watch what I'm going to do with my juice. You watching? OK. Now, this is your juice, and this is my juice. Do we still have the same amount of juice to drink?

Matee: Yes.

Instructor: How do you know we have the same amount to drink?

Matee: Well, we don't have the same amount to drink, because this one is a littler cup than this one.

Instructor: We do not have the same amount to drink? Who has more?

Matee: Me.

Instructor: How can you tell me you have more?

Matee: Because see, this.

Instructor: Mm-hmm. Oh. I see. So is it this one comes up higher?

Matee: Yeah.

Instructor: And that's how you can tell that you have more? OK. Well I don't know. Now, I'm going to pour my juice back in here.

Matee: There is spilling.

Instructor: I know. I spilled just a tiny bit right there.

Matee: And over there.

Instructor: That was from before. Now, do we have the same amount to drink?

Matee: We still have the same amount.

Instructor: How can you tell we have the same amount? Just tell me.

Matee: Yes. Just check that we're right.

Instructor: OK. Check.

Matee: We do have the same amount.

Instructor: Very good, Matee. Thank you so much.
