    Cuatro que ya tenemos o podemos . . . 
    żVes? Nada mas necesitamos uno. [English
    translated from Spanish: Four that we now 
    have or we can . . . See? We only need 
    one.]Ana:
    Pero no sabemos . . . ella quiere saber
    cuantos pueden caber adentro. [But we do 
    not know . . . She wants to know how 
    many can fit inside . . .] How many do 
    you think these fit in this?Carlos:
    Did you understand that?Ms. Smith:
    And who would like to share something 
    that they found out with their partner?Juan:
    Um, it takes, um, 125 small cubes to
    make a whole yellow one, a whole big 
    cube.  Okay?David:
    It does not.
    
Ms. S.:
    Now, as you're saying that I notice your
    partner's going "No, it doesn't."  What, 
    did you two
    
David:
    No it doesn't because--
    
Ms. S.:
    [Simultaneously] have a disagreement 
    about it?
    
David:
    It . . . it takes five cubes to . . . 
    to get, um, . . .
    
Bill:
    One side.
    
David:
    . . . one side.
    
Ms. S.:
    'Kay.
    
David:
    And fi-, five times five equals 25, and 
    it has six sides.  Um . . .
    
Ms. S.:
    So, what did you--
    
David:
    25 times six equals 150.  And, and that's
    a hun-, so the 150, but you have to fill 
    the inside.  So we, so I think it, I 
    think it's like 200, maybe.
    
Ms. S.:
    Are you definite on 200, or are you 
    estimating this?
    
David:
    No, I, I'm estimating.
    
Ms. S.:
    Okay.
