Instructor 1:  We’re gonna play “Four the Win,” and if you remember, there’s two parts to this game. First we have to find the match, and then second, we’re going to make something new to match the missing one, okay? So here’s what I have for us today:

I have 27-10, 10+27, and then we have a word problem down here. Let’s look at the word problem and let’s see which one it matches.

Rory ate 10 chips. When he started, he had 27 chips. How many does he have now? What number problem do you think it matches?

Student 1: 27-10.

Instructor 1: How did you think about that?

Student 1: Because he had 27 chips at the start. He ate it, so he ate 10 and that means 27–he already had 27 but ate 10 so minus 10. And it says 27-10 right there.

Instructor 1: So you think the 27-10 matches that situation. What do you think? You agree?

Student 2: Yes.

Instructor 1: Okay, now guess what? That means 10+27 doesn’t have a partner yet. It doesn’t have a match. Let’s try to come up with a situation that would match 10+27. Let’s think about it for a second.

Instructor 2: Okay guys, so for this activity, you can flip over your papers. You’re gonna see different–either a word problem or an equation and then you’re going to have a blank space there. You see the word problem? You have to find the match, right? It’s either one or the other in terms of the two equations and then there’s going to be one equation that’s going to be left unmatched. For that equation, you have to create a match that corresponds to that one. Any questions? Ready? Go ahead.

Which of the two equations matches that word problem?

Student 3: I said y=5x+23 because she already has an initial amount of 23 saved up and for every week she saves $5. So X would be the amount of weeks and Y would be the amount of money Sarah gets. And I got y=5x+23 which matches the one right next to it.

Instructor 2: So how about the match for the unmatched element was y=23x+5. Did you all create a match for that?

Student 4: I said recently, Tom started a new job and he earns $23 an hour, and he already has $5 saved up.

Instructor 2: I think we have what we needed. You did a great job in this “Four the Win” activity. We are now going to transition to the next one.
