Presentation Overview
Why focus on Children’s Mathematical Thinking Adding it Up Equity
Making use of the development of children’s mathematical thinking Research findings
Supporting the development of children’s mathematical thinking in classrooms
Considering Understanding: Adding it Up Recognizing that no term captures
completely all aspects of expertise, competence, knowledge, and facility in mathematics, we have chosen mathematical proficiency
five interwoven, interdependent strands: conceptual understanding, procedural fluency, strategic competence, adaptive reasoning, productive disposition.
Mathematical proficiency is not a one-dimensional trait, and it cannot be achieved by focusing on just one or two of these strands
About children’s thinking Children come to school
with mathematical knowledge
Children’s knowledge develops through well documented trajectories
Development of children’s thinking quite robust
Development of children’s thinking does not match the way adults solve problems

Experimental Study
Learning about the development of students’ mathematical thinking in classrooms
Development of tools to support learning in practice
Development of communities of inquiry
Evidence that Attending to Student Thinking Can Make a Difference CGI provides evidence that teachers’
classroom practice that
includes eliciting and making public student thinking,
involves eliciting multiple strategies, focuses on solving word problems and uses what is heard from students to make
instructional decisions
leads to the development of student understanding
Evidence that Attending to Student Thinking Can Make a Difference
Teachers who drew on
detailed knowledge of the development of students’ mathematical thinking within a domain
an organization of student thinking in relation to the mathematical content
notions that they could continue to learn from their practice …identity
supported the development of student understanding
Supporting teachers to make use of students’ mathematical thinking There is no single pattern or trajectory for
teachers as they come to make use of children’s thinking
Can get teachers to ask students how they solved problems
Challenging to support teachers to make use of what they hear from students, to engage students in comparing strategies, to move forward in their trajectories
Moving forward…learning more to support teacher learning and practice Pushing on the research
Learning through professional development
Moving towards understanding the details of practice through research
Listening to students talk makes it possible for the teachers (and other students) to monitor students’ mathematical thinking
The act of talking can itself help students develop improved understanding
Explaining to other students is positively related to achievement outcomes, even when controlling for prior achievement (Brown & Palincsar, 1989; Fuchs, Fuchs, Hamlett, Phillips, Karns, & Dutka, 1997; King, 1992;
Nattiv, 1994; Peterson, Janicki, & Swing, 1981; Saxe, Gearhart, Note, & Paduano, 1993; Slavin, 1987; Webb, 1991; Yackel, Cobb, Wood, Wheatley, & Merkel, 1990).
Less is known about teacher practices that are most effective for producing high-level discourse in the classroom
Details: Supporting the development of students’ mathematical thinking
In classrooms where:Students gave correct and complete explanations Students scored the highest on the assessments
Teachers: Used a fairly coherent set of problems Asked questions very specific to what students said Engaged students in thinking and talking about
important mathematical ideas arising out of their suggestions
All students participated in conversations about the mathematics
Learning through professional development
develop relationships: create a community where teachers can learn together about the teaching and learning of mathematics
where the activities of the community were embedded in teachers’ everyday work
make space for teachers to share their histories and make their practice public
focus on the details and structures around students’ mathematical thinking
Focus on what students can do (Counter-storytelling) attention to the artifacts and language that support the
development of students’ mathematical thinking in practice
Artifacts in our Professional Development work…
Framework for the development of student strategies within mathematical domains
• Problem types • Video of students and
classrooms • Language
How did you get that? Does that always work? Strategy and problem names
Number sentence index cards

Artifact Travel
Ongoing use across settings
Attention to and unpacking of classroom use in PD
Trace where we are with ideas around artifact
Helps to see teacher use of artifact in both PD and classrooms – raise questions, note inconsistencies, conflict etc..
How artifacts support learning and practice
Focused on creating and negotiating meaning
Focused conversation across and within communities of practice
Supported the development of language and interaction that could be used to support the development of new relationships
Supported story telling across boundaries and be used to develop counter stories
Purposeful
Challenged the existing cultural practices
Development of Children’s Mathematical Thinking
Tom has 102 dog biscuits. His Dog Harmony eats 12 biscuits a day. How many days will it take Harmony to eat all of the dog biscuits?
Let’s see what children can do…
Attending to the Details of Children’s Mathematical Thinking Allows Teachers to:
Notice what students can do
Make decisions that build on what students know
Create openings for varied participation
Support the development of students who think of themselves as capable of making sense of mathematics
Development of Children’s Mathematical Thinking
Lucy had 38 dollars. One weekend she earned 25 making dollars raking leaves for her neighbors. How much money did Lucy have then?
Watch what children can do…What can you do?
Count by tens, solve problems using 20 and 30, take numbers apart and put them back together.
Mathematical Proficiency
conceptual understanding—comprehension of mathematical concepts, operations, and relations
procedural fluency—skill in carrying out procedures flexibly, accurately, efficiently, and appropriately
strategic competence—ability to formulate, represent, and solve mathematical problems
adaptive reasoning—capacity for logical thought, reflection, explanation, and justification
productive disposition—habitual inclination to see mathematics as sensible, useful, and worthwhile, coupled with a belief in diligence and one’s own efficacy.

Evidence that Attending to Student Thinking Can Make a Difference
Students constantly surprise us…

Focusing on Making Student Thinking Explicit need to be able to use student strategies as
the center of the workgroup conversation, as one of the tools teachers interact with
expertise shared change in power structures, teacher as
expert provides an explicit trace of the group’s
thinking extends to other communities of practice centers the role of the professional developer
Moving Towards the Details of Practice
Need to know more about student participation in mathematics classrooms if we are to support teaching
Often large scale studies focus on what occurs in public discourse
Smaller scale studies document more specifically student participation and what that means for student learning Forman, et al, 1998; Lampert, 2001; Moschkovich, 2002; O’Connor & Michaels, 1996; Palincsar & Brown, 1984, 1989; Yackel, Cobb, & Wood, 1991
Want to look to the relationship between student participation, teaching, the mathematics and student outcomes
