DescriptionResearcher Maher began the session by discussing the ideas that the students had worked on during the previous session. Then, the students worked in groups and revisited the task: Which is larger, one half or three fourths, and by how much? This task had been introduced during the previous session, and the students were again encouraged to build multiple models to show their solutions. Several students joined forced to build large models to represent their solution. Two groups successfully built models that showed the difference between the two fractions as four forty-eighths, using a forty-eight cm long model. These students then worked on finding appropriate number names for each rod in their model.
