DescriptionIn this clip, researcher Alice Alston leads a discussion about how many towers could be built three cubes high when selecting from two colors. In the previous clip, the students had discussed their solutions to the problem of how many towers could be created four cubes high when selecting from two colors. The researcher questions the students about whether they think there would more or less than sixteen towers. The answers she receives vary; some students believe there would be more, some believe there would the same, and some believe there would be fewer. The students then demonstrate examples of towers three cubes high. The researcher asks the students to talk with their partners to guess how many towers they could create three cubes tall. She records some of the students’ guesses on the board, with one pair of students guessing twenty and some other groups of students guessing sixteen towers.
