Abstract
(type = summary)
In the first of three clips from a single class session, the researcher asks the 4th grade students to explain the mathematical task of the previous day when each of the three small groups within the class had been presented with a chocolate bar and asked to divide it equally among the members of its group. Andrew reported that his group of 9 students had divided the candy bar into 10 equal pieces and that each student received 1 and 1/9 pieces. Jessica explained that her group of 8 students had also divided the candy bar into 10 pieces and that each student received 1 and 1/4 pieces. Kimberly reported that her group also included 8 students and agreed with Jessica’s solution. The class agreed that the students in the groups of 8 had received a larger amount of candy. When asked how much larger, Meredith conjectured that the difference was 1/5, and the class concurred. Discussion followed about this conjecture and the students were challenged to build models with the rods to justify their solutions to the problem.
Problem Statement: If we agree that the 8 students who received 1 and 1/4 pieces of candy got more than the 9 students who received 1 and 1/9 pieces, how much more did each of the students in the group of 8 receive? How much larger is 1/4 than 1/9?
