**In This Session:**

**Part A:** Observing a Case Study

**Part B:** Reasoning About Number and Operations

**Part C:** Problems That Illustrate Reasoning About Number and Operations

**Homework**

In the previous sessions, you explored number and operations as a mathematics learner, both to analyze your own approach to solving problems and to gain some insight into your personal conception of number and operations. It may have been difficult to separate your thinking as a mathematics learner from your thinking as a mathematics teacher — most teachers think about teaching as they are learning and think about learning as they are teaching. In this session, we shift the focus to your own classroom and to the approaches your students might take to mathematical tasks involving number and operations concepts.

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

**Learning Objectives**

In this session, you will do the following:

- Explore the development of number and operations concepts at your grade level
- Examine children’s understanding of number and operations concepts
- Explore how you would teach problems involving different number and operations concepts
