Supporting Rigorous Mathematics Teaching and Learning Tennessee Department of Education Elementary School Mathematics Grade 1 Academically Productive Talk in Mathematics: A Means of Making Sense of Mathematical Ideas

Rationale Effective teaching requires being able to support students as they work on challenging tasks without taking over the process of thinking for them (NCTM, 2000). Building a practice of engaging students in academically rigorous tasks supported by Accountable Talk®discourse facilitates effective teaching. Students develop an understanding of mathematical ideas, strategies, and representations and teachers gain insights into what students know and what they can do. These insights prepare teachers to consider ways that advance student understanding of mathematical ideas, strategies, or connections to representations. Today, by analyzing math classroom discussions, teachers will study how Accountable Talk discussion supports student learning and helps teachers to maintain the cognitive demand of the task.

Session Goals Participants will: learn a set of Accountable Talk features and indicators; and recognize Accountable Talk stems for each of the features of talk, and consider the potential benefit of posting and practicing talk stems with students.

Overview of Activities • Participants will: • discuss Accountable Talk features and indicators; • discuss students’ solution paths for a task; • analyze and identify Accountable Talk features and indicators in a lesson; and • plan for an Accountable Talk discussion.

Accountable TalkFeatures and Indicators

Accountable Talk Discussion • Study the Accountable Talkfeatures and indicators. • Turn and Talk with your partner about what you would expect teachers and students to be saying during an Accountable Talk discussion for each of the features. • accountability to the learningcommunity • accountability to accurate, relevant knowledge • accountability to discipline-specific standards of rigorous thinking

AccountableTalk Discussion Indicators for all three features must be present in order for the discussion to be an “Accountable Talk Discussion.” • accountability to the learning community • accountability to accurate, relevant knowledge • accountability to discipline-specific standards of rigorous thinking Why might this be important?

Accountable Talk Features and Indicators Accountability to the Learning Community • Active participation in classroom talk. • Listen attentively. • Elaborate and build on each others’ ideas. • Work to clarify or expand a proposition. Accountability to Knowledge • Specific and accurate knowledge. • Appropriate evidence for claims and arguments. • Commitment to getting it right. Accountability to Rigorous Thinking • Synthesize several sources of information. • Construct explanations and test understanding of concepts. • Formulate conjectures and hypotheses. • Employ generally accepted standards of reasoning. • Challenge the quality of evidence and reasoning.

Accountable Talk Starters Work in triads. On your chart paper, write talk starters for the Accountable Talk indicators. A talk starter is the start of a sentence that you might hear from students if they are holding themselves accountable for using Accountable Talk moves. e.g., I want to add on to ______ (Community move). The denominator of a fraction tells us _____ (Knowledge move). The two equations are equivalent because ____ (Rigor move). (Work for 5 minutes.)

Accountable TalkStarters • What do you notice about the talk starts for the: • accountability to the learning community • accountability to accurate, relevant knowledge • accountability to discipline-specific standards of rigorous thinking • What is the distinction between the stems for knowledge and those for rigorous thinking? • Why should we pay attention to this?

Preparing to AnalyzeAccountable Talk Features and Indicators in Classroom Practice

The Make a Ten Task Use the interlinking cubes to make a structure of ten. Write a number sentence to describe your structure of ten. Draw a picture for your structure of ten. Make a second structure of ten that looks different from your first structure of ten. Write a different number sentence for this structure of ten.

Solve the Task(Private Think Time and Small Group Time) • Work privately. Analyze the student work for The Make a Ten Task in your participant handout. • Work with others at your table. Hold yourselves accountable for engaging in an Accountable Talk discussionwhen you discuss the student work. • What do the students understand? How do you know? • How does one solution path differ from the other? • What might be used in the student work to prompt students to think about and discuss the ideas articulated in the standards?

Context for the Make a Ten Lesson Teacher: Jennifer DiBrienza School: PS 116 District: New York City, District 2 Grade Level: First Grade The lesson was conducted in a first grade classroom. The students have worked with interlocking cubes many times. They have explored ways in which they can use the blocks to make different shapes. They have described the figures that they can make with the interlocking cubes. In this lesson, we observe the Share, Discuss, and Analyze phase of the lesson. The students have worked independently to create two different structures and to write number sentences to describe their structures. Now the students come together to share and discuss each other’s structures.

Accountable Talk Discussion Successful teachers are skillful in building shared contexts of the mind (not merely assuming them) and assuring that there is equity and access to these experiences. Talk about these experiences for all members of the classroom are a necessary part of the experience. Over time, these contexts of the mind and collective experiences with talk lead to the development of a "discourse community"—with shared understandings, ways of speaking, and new discursive tools with which to explore and generate knowledge. In this way, an intellectual "commonwealth" can be built on a base of tremendous sociocultural diversity. Accountable Talk℠ Sourcebook: For Classroom Conversation that Works (IFL, 2010)

Giving it a Go: Planning for an Accountable Talk Discussion Identify a person who will be the teacher of the lesson. Others in the group will engage in the lesson once the lesson has been planned. Plan the lesson together. Actually write questions that the teacher will ask and anticipate participant responses.

Focus of Lesson Students share two structures. The teacher’s goal for the lesson is to help students understand the connections between the two structures. (Associative Property of Addition) (2 + 5) + 3 and 2 + (5 + 3).

Reflecting on the Accountable Talk Discussion Step back from the discussion. What are some patterns that you notice? What mathematical ideas does the teacher want students to discover and discuss?

A Wondering… • What will you keep in mind when attempting to engage students in Accountable Talk discussions? • What does it take to maintain the demands of a cognitively demanding task during the lesson so that you have a rigorous mathematics lesson? • What role does talk play?

Bridge to Practice • Plan a lesson with colleagues. Select a high-level task. • Anticipate student responses. Discuss ways in which you will engage students in talk that is accountable to the learning community, to knowledge, and to standards of rigorous thinking. Specifically, list the moves and the questions that you will ask during the lesson. • Engage students in an Accountable Talk discussion. Ask a colleague to scribe a segment of your lesson, or audio or video tape your own lesson and transcribe it later. • Analyze the Accountable Talk discussion in the transcribed segment of the talk. Identify talk moves and the purpose that the moves served in the lesson. Have a segment of the transcript so you can identify specific moves.
