DescriptionIn this second of five clips from a single class session, the students consider how 3 candy bars could have been equally distributed among their class of 25. The students had worked on this problem in the previous session when they were asked to share a single candy bar equally among the students in their small group. Since two groups were composed of 8 students while the third was composed of 9 students, their task had been to determine how much more candy each person in the smaller group would receive than those in the larger group. Jessica begins this clip suggesting that the earlier distribution was not equitable thabut t the portions had to be different due to their being an odd number of students in the class. Andrew suggests that the 3 candy bars could be divided into 30 rectangular pieces (10 per candy bar) and shared evenly among all 25 students by having each student get one whole rectangular piece and 1/5 of one of the remaining 5 rectangular pieces.
Problem Statement: How can you share 3 candy bars evenly among the 25 students in your class? How much candy would each student receive?.
