We’ll be away next week, at the NCSM and NCTM conferences in Washington DC. We’d love to see you at one of our Sessions, or at the TERC booth!

**Session 1317: But Why Does It Work?: Using Examples to Investigate Structure**

Many students appear to know how to compute, but what do they understand about the underlying structure of the operations? This talk will use evidence from our classroom-based research, including video clips, to show how, through reasoning about what appear to be simple examples, students dig more deeply into mathematical structure. Participants will also examine how teachers develop a collaborative and invitational context that encourages the range of students to work together on significant mathematics about the behavior and properties of the operations.

**Presenter: **Susan Jo Russell

**Time: **11:15-12:15

**Location: **147B

**Session 2302: Looking for Structure: Early Algebra with a Focus on the Operations**

Although K-6 mathematics focuses on calculation, the meaning of the operations may fall into the background. Indeed, many common errors stem from confusion about which structures apply to which operation. This session will present classroom examples to illustrate how early algebra can provide a context for highlighting the operations as distinct objects. The examples emphasize the role of representations in the study of structure and teachers’ actions that draw students’ attention to those structures.

**Presenter:** Deborah Schifter

**Time:** 11:15-12:15

**Session 3131: Doing the Math with Paraeducators**

This session will share components and initial findings from our project, Doing the Math with Paraeducators. We will focus on the roles paraeducators play in classrooms and on our practice-based professional development designed to address the current inequities by developing paraeducator confidence, pedagogy and mathematics content knowledge.

**Presenters:** Judy Storeygard and Denise Treacy

**Time:** 8:45-9:45

**Location:** Room 143A

**Session 3325: Math Practices in the Classroom: What Students Do and What Teachers Do to Make It Happen**

Using video footage, we will examine how the Standards for Mathematical Practice (SMP) are enacted. We will look closely at the students’ reasoning and how they engage with the mathematics. Then we will analyze teacher moves that support student SMP enactment. Participants will come away with a deeper understanding of what the Practices look like, and how to support their students in making sense, persevering, and constructing arguments.

**Presenters:** Annie Sussman and Deborah Schifter

**Time:** 11:15-12:15

**Location:** 151B

Very good

I am a student of mathematics and I am very interested in mathematics

Math is one of the sweetest sciences

Thank you for your work
