DescriptionThis session marked a departure from those preceding it as it centered around a different activity. Instead of using Cuisenaire rods to represent fractions, the students were provided ribbons, meter sticks, and string, and were asked to form bows of specific fraction lengths from different lengths of ribbon. Also, in addition to the researchers and teacher present, several visitors were in the classroom and spoke with the students as they worked on the tasks. After Carolyn Maher introduced the visitors, the students worked with their partners to solve several series of tasks. For the first set of tasks, the students were asked to find the number of bows that could be made from white ribbon, which measured one meter in length, if the bows were to be one half, one third, one fourth, and one fifth meters long. For the second set of tasks , the students were asked to find the number of bows of those lengths that could be made from blue ribbon, which measured two meters in lengths. The last part of that set of tasks asked the students to also consider making bows that were two thirds of a meter in length from the blue ribbon. The third set of tasks asked the students to form bows from gold ribbon, which measured three meters in length. Finally, the fourth set of tasks required the students to consider using six-meter-long red ribbon to make bows. The students recorded their responses on a worksheet that enabled them to see the patterns inherent in each set of tasks. Carolyn Maher then conducted a whole class discussion, during which the students shared their solutions and justifications to the tasks.
