DescriptionIn the first clip from this session, researcher Carolyn Maher reminded the students that they had compared the fractional numbers one half and one third. For homework they had written about their solution to the task of finding the difference between those numbers. Some students had come up with the solution of one sixth as the difference between them. Researcher Maher then said that she would like them to write about someone else’s solution that they agreed with or to write about someone else’s solution and show how they disagreed with the other student’s argument. Researcher Maher explained to the class that mathematicians sometimes show that another’s arguments don’t make sense. Researchers Robert B. Davis and Amy Martino are observing.
