Write a paper in which you describe :
- how the students' spatial reasoning evolved over the course of the three lessons (including both whole-class and small-group episodes) and
- how the instructional activities supported the development of spatial reasoning and spatial sense.
In your report, be sure to give specific examples by referring to the lesson plan, classroom events, the teacher's comments, and the students' small-group work. In addition to the paper, you are expected to present an overview of your analysis to the class and to facilitate discussion on your topic.
