DescriptionThe session began with a whole class discussion about the problems that the students had worked on the day before. Afterwards, the students worked with their partners on two series of tasks. These were:
1) How many bows can you make from ribbon that's a third of a meter in length if you have nine meters of ribbon? How many bows can be made that are three meters in length?
2) How many bows can be made from twelve meters of ribbon that are one half meters in length? How many ribbons that are two meters in length? How many ribbons that are two thirds meters in length?
The students used drawings to show their solution, and the class culminated in a presentation of various students' solutions to the problems. Carolyn Maher asked the students to think about whether the pattern that had been found in the solutions during previous sessions held for the tasks that they had worked on that day.
