Common Core Six Instructional Shifts in MathShift 1 - Focus Teachers use the power of the eraser and significantly narrow and deepen the scope of how time and energy is spent in the math classroom. They do so in order to focus deeply on only the concepts that are prioritized in the standards so that students reach strong foundational knowledge and deep conceptual understanding and are able to transfer mathematical skills and understanding across concepts and grades.
Shift 2 - Coherence Principals and teachers carefully connect the learning within and across grades so that, for example, fractions or multiplication spiral across grade levels and students can build new understanding onto foundations built in previous years. Teachers can begin to count on deep conceptual understanding of core content and build on it. Each standard is not a new event, but an extension of previous learning.
Shift 3 - Fluency Students are expected to have speed and accuracy with simple calculations; teachers structure class time and/or homework time for students to memorize, through repetition, core functions (found in the attached list of fluencies) such as multiplication tables so that they are more able to understand and manipulate more complex concepts.
CFN 208 CFN 208 Coach/Assistant Principal/Teacher-Leader Coach/Assistant Principal/Teacher-Leader Mathematics Network MeetingMathematics Network MeetingThursday, October 13, 2011Thursday, October 13, 2011
Common Core Six Instructional Shifts in MathShift 4 - Deep Understanding Teachers teach more than “how to get the answer” and instead support students’ ability to access concepts from a number of perspectives so that students are able to see math as more than a set of mnemonics or discrete procedures. Students demonstrate deep conceptual understanding of core math concepts by applying them to new situations. As well as writing and speaking about their understanding.
Shift 5 – Applications Students are expected to use math and choose the appropriate concept for application even when they are not prompted to do so. Teachers provide opportunities at all grade levels for students to apply math concepts in “real world” situations. Teachers in content areas outside of math, particularly science, ensure that students are using math – at all grade levels – to make meaning of and access content.
Shift 6 - Dual Intensity Students are practicing and understanding. There is more than a balance between these two things in the classroom – both are occurring with intensity. Teachers create opportunities for students to participate in “drills” and make use of those skills through extended application of math concepts. The amount of time and energy spent practicing and understanding learning environments is driven by the specific mathematical concept and therefore, varies throughout the given school year

NYSED Common Core State Standards (CCSS) for ELA/ Literacy, Math, and the ArtsImplementation Timeline
SY 2011- 2012 • Recommend initial phase of CCSS implementation: every teacher is delivering at least one CCSS aligned unit each semester. • Math and ELA tests continue to be aligned with 2005 Standards • Vendors who will collaborate with NYS educators to develop curricular modules in ELA, Math, and the Arts are chosen between September and January and their submissions (several exemplary units) are immediately made available to the field Summer 2012 • The first 50% of ELA, Math, and Arts exemplary modules are in the field from the vendor. The nature and number of these modules is linked w/the common core-aligned tests to come in 12-13. • Additional training on CCSS occurs • Intensive training on the nature of the transition in the SY 12-13 tests occurs SY 2012-2013 • Phase II of CCSS implementation happens in schools • NYS tests aligned to CCSS in ELA and Math begin Summer 2013 • Full menu of ELA, Math, and Arts exemplary units are available • Ongoing training on curriculum and testing SY 2013-2014 • Phase III of CCSS implementation happens in schools • NYS Tests aligned to CCSS in ELA and Math Summer 2014 • Ongoing training on CCSS implementation • Intensive training on PARCC assessments (if adopted by the Board of Regents) SY 2014-15 • Full implementation of CCSS • PARCC assessments (if adopted by the Board of Regents)
CITYWIDE INSTRUCTIONAL EXPECTATIONS for 2011 -2012FINAL June 1, 2011*Strengthening student work by examining and refining curriculum, assessment, and classroom instruction; and*Strengthening teacher practice by examining and refining the feedback teachers receive. *Rigorous Curriculum and Tasks for All Students *In teams, look closely at current student work to understand the steps needed to reach the level of performance that the Common Core demands (spring/fall 2011). *Engage all students in at least one literacy task and one math task aligned to strategically selected Common Core standards. These tasks should be embedded in Common Core-aligned curricula and include multiple entry points for all learners, including students with disabilities and English language learners (winter 2011-12). – In literacy, students will complete a task that asks them to read and analyze informational texts and write opinions and arguments in response. – In math, students will engage in a cognitively demanding mathematics task that requires them to demonstrate their ability to model with mathematics and/or construct and explore the reasoning behind arguments to arrive at a viable solution. *In teams, look closely at resulting student work to continue the cycle of inquiry, making future instructional adjustments and communicating lessons learned to other school staff (spring 2012).

Rationale for Selected Common Core Standards in MathematicsThe Standards for Mathematical Practices are one of the most distinct portions of the Common Core standards. Taken together, these standards paint a picture of a mathematically proficient student. We understand that the Standards for Mathematical Practice are interconnected and that a rich task may require students to demonstrate many of the practices. However, for the winter task, we ask that schools focus on one or both of the high-leverage practices we’ve selected—Model with Mathematics (#4) and Construct Viable Arguments and Critique the Reasoning of Others (#3)—and the domains of focus representing key content in each grade. Modeling is what real mathematicians do: using mathematics to represent and solve authentic problems in our world. Key to this process of problem solving is the ability to clearly construct and analyze mathematical arguments, evaluating and articulating the reasoning behind claims. Facility with these two practices, and solid knowledge of key concepts, will enable students to demonstrate their mathematical thinking by successfully analyzing authentic problems and constructing and defending logical paths to solving problems.

SEVEN STEPS FOR ALIGNING MATHEMATICS TASKS TO THE CCLS
The diagram below shows the plan for some empty lots in a neighborhood. They are formed with the same properties as your pattern blocks. (This means that the trapezoids are congruent and the triangle, parallelograms, and hexagons are equilateral.) Mike and Juan are going to clean the lots by removing papers, bottles, and cans. Each lot they clean will earn them points in a contest. If they earn a total of at least 75 points they will win a prize. a) If Lot D is worth 20 points to clean up, what is the fair value of the other lots? Show all your mathematical thinking. b) If Mike and Juan clean up all the lots, will they have earned enough points to win the prize? Justify your answer using your mathematical thinking.
