Geometry Session 10, Grades K-2

In the previous sessions, we explored geometry as a problem-solving process. You put yourself in the position of a mathematics learner, both to analyze your individual approach to solving problems and to get some insights into your own conception of geometric reasoning. It may have been difficult to separate your thinking as a mathematics learner from your thinking as a mathematics teacher. Not surprisingly, this is often the case! In this session, however, we will shift the focus to your own classroom and to the approaches your students might take to mathematical tasks involving geometry.

Part A:
Geometry as a Problem-Solving Process

Part B:
Developing Geometric Reasoning

Part C:
Activities That Illustrate Geometric Reasoning

Homework

As in other sessions, you will be prompted to view short video segments throughout the session; you may also choose to watch the full-length video for this session.
Note 1

In this session, you will do the following:
•	Explore the development of geometric reasoning at your grade level, including the van Hiele model of geometric learning
•	Review mathematical tasks and their connection to the mathematical themes in the course
•	Examine children's understanding of geometric concepts


	Throughout the session you will be prompted to view short video segments. In addition to these excerpts, you may choose to watch the full-length video of this session.
