DESCRIPTION
Why Focus on Connections & Coherence? “When students can connect mathematical ideas, their understanding is deeper and more lasting.” (NCTM, 2000 p.64) “When students understand the interrelatedness of mathematics, they often have many more strategies available to them when solving problems and insights into mathematical relationships.” (Hiebert, 1997) “Through instruction that emphasizes the interrelatedness of mathematical ideas, students not only learn mathematics they also learn about the utility of mathematics.” (NCTM, 2000, p.64) “Toward greater focus and coherence...” (CCSS, p. 5)

Focusing on Reasoning and ProvingYear 3
1. What is reasoning and proving?2. How do students benefit from
engaging in reasoning and proving while studying algebra?
3. How can teachers support the development of students’ capacity to reason-and-prove across grades 7 - 11?

Working to build coherence & connections with these tools
• Anchor Tasks with Corresponding Analysis Protocols
• Teaching & Learning Trajectories (TLT)

DELTA Data Collection
Please take about 45 minutes to complete the toothpick task and answer the corresponding pedagogical questions.
Kitten Task
Work out whether this number of descendants is realistic.Here are some facts that you will need:
Review the student work and write comments attending to the following features.
• What has a particular student done correctly?
• What assumptions has he or she made while working to solve the task?
• What does the student need to improve/learn? What might you do to support this student?
Using Student Work to Guide Instruction:Classroom Level
• The student has selected the important facts and used them to solve the problem.
• The student is aware of the assumptions he or she has made and the effect these assumptions have on the result.
• The student has used more than one method
• The student appears to have checked whether his or her results make sense and have improved upon a method if need be.
• The student has presented his or her results in a way that will make sense to others.
Using Student Work to Guide Instruction:Classroom Level
Working to build coherence & connections at two levels
• Work at the classroom level:− Task selection− Assessment for learning− Identifying misconceptions− Connecting to prior knowledge and
future lessons (mathematical language, tasks, strategies)
• Work at the systems level: – Course curriculum design within and across grades/courses– Course offerings (tracking, acceleration, integrated content)– District Assessment Systems– Collegial conversations within and across grades/courses (District
Dialogues)
In small groups, analyze student work using the following sorting schema:
Sort 1: Argument is attentive to nearly all parameters
Sort 2: Mathematically productive solution strategy is attempted based on analysis of situations/cases
Sort 3: Reasoning used to support the conclusion is logical
Using Student Work to Guide Instruction:Systems Level
Using Student Work to Guide Instruction:Systems Level
Please be specific as you summarize your across grade level findings:
•What do your students seem to understand?
•What do they have yet to understand?
•What implications do these findings have at the systems level?
Student Work Analysis:Reflection
Compare this sorting activity to prior data analysis you have done at the classroom and systems levels.•In what ways has this process prompted you to consider how you attend to students’understanding and use of mathematics?
Driving Questions for Teachers
• How do we “cover” so much content in each secondary grade/course with deep understanding?
• What does it mean to teach algebra in 7th grade, 8th grade, Algebra I and Algebra II? What portion should I be teaching?
• Are there algebraic connections to lessons in earlier grades that I could be drawing on to help teach my content?
• Are there ways to support my students’ understanding and use of the Standards for Mathematical Practice?
Shifting Focus from Content to Practices
Content-Focused Teaching and Learning Trajectories – Years 1 and 2•Rate of Change•Solving Linear •Solving Quadratic•Data Analysis•Equivalence
Practice-Focused Teaching and Learning Trajectories – Year 3•Reasoning-and-Proving
District Dialogues
1. Individually, take a few minutes to reflect on your team’s learning throughout the project.
2. As a team, discuss what you have accomplished and in what ways you intend to work together as you continue to grow professionally. Please keep a record of your group’s ideas to reference in the future.
3. Be prepared to share a couple of key points from your conversation.
Team Reflection
End-of-Day Reflection
1. Are there any aspects of your own thinking and/or practice that our work throughout the project has caused you to consider or reconsider? Explain.
2. Are there any aspects of your students’ mathematical learning that our work throughout the project has caused you to consider or reconsider? Explain.
