Deep Dive into the Math Shifts
Understanding Focus and Coherence in the Common Core State Standards for
Mathematics
The Three Shifts in Mathematics
•Focus: Strongly where the standards focus•Coherence: Think across grades and link to major topics within grades•Rigor: Require conceptual understanding, fluency, and application
Engaging with the 6-8 Content
• How would you summarize the major work of grades 6-8?
• What would you have expected to be a part of the major work that is not?
• Give an example of how you would approach something differently in your teaching if you thought of it as supporting the major work, instead of being a separate, discrete topic.

Engaging with the HS Content
• How would you summarize the major work of Algebra I and Geometry?
• What would you have expected to be a part of the major work that is not?
• Give an example of how you would approach something differently in your teaching if you thought of it as supporting the major work, instead of being a separate, discrete topic.
Coherence Across and Within Grades
• It’s about math making sense.• The power and elegance of math comes out
through carefully laid progressions and connections within grades.
Taken from the M/J Pre- Algebra Course Description on C-Palms website: Don’t … Sort clusters from Major to Supporting, and then teach them in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
Looking For Coherence Within Grades
• Examples: 6th grade: Solve problems by graphing in all 4
quadrants. (1st year of rational numbers) 8th grade: “Understand the connections between
proportional relationships, lines and linear equations.”
Algebra 1: Represent data on two quantitative variables on a scatter plot, and describe how the variables are related
Coherence Within A Grade
Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

Coherence Within Geometry
Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure using, e.g., graph paper, tracing paper, or geometry software. Specify a sequence of transformations that will carry a given figure onto another.

Looking for Coherence Across Grades
• Coherence is an important design element of the standards.
• “The Standards are not so much built from topics as they are woven out of progressions.”
DIVING IN! Let’s explore for evidence of coherence!
Coherence Card ActivityActivity: Place the standards of each theme under the
appropriate grade or course.
– Separate the cards by theme.– No grade has two of the same theme.– Some “themes” that have only a few cards might represent
consecutive grades and some may not.– Read each card in it’s entirety to help determine placement.– Do not check your Standards until you and your colleagues agree
on the final product.– Discuss horizontal and vertical observations with your partners.

Engaging with the Content• Review your work on Coherence.
• Revisit the major focus of each grade/course
• Which standards in your progressions are part of the major work, the supporting work, or additional work? Mark them appropriately on your posters using green, blue, or yellow makers.
• Discuss the connection between focus and coherence and how the two work in tandem to influence instruction
