UG = undergraduate, L = Lisa
1 UG: Multiples of two.
2 L: (Munches a two, moves two spaces right then munches another two, then moves one more space for a third two.)
3 UG: Yummy (laughs).
4 L: (inaudible)
5 UG: Do you? Huh? (inaudible)
6 L: (Skips over an eight and a ten, then munches a two.)
7 UG: Ten, not three, uh oh.
8 L: (Skips over three. Keeps moving her character around the screen.)
9 UG: OK what else does-- Is ten a factor of two, a multiple of two?
10 L: I don't know.
11 UG: If you multiply five times two, you get ten. So ten is a multiple of two. So you can eat all the tens.
12 L: (Passes over some tens.) Should I eat tens?
13 UG: Yes!
14 L: (Eats a ten.)
15 UG: Uh-oh. Great troggle man is coming!
16 L: (Moves her character away, passing over eights).
17 UG: Do you know how to count by two?
18 L: (Shakes her head from sides to side.)
19 UG: No? OK, well even numbers are multiples of two: so ten and six and eight also. They are all multiples of two.
