Elementary School Pajaro Valley Unified School District Number
Talks & Mathematical Practices
Slide 2
Description of Practice In Number Talks, students gather in a
centralized area on the floor, a sequence of problems are given one
at a time that are intended to provide students with opportunities
to discover mathematical relationships within the sequence of
problems. Students are taught common hand signals to communicate
their understanding which also aids with formative assessments for
the teacher. Students debate the solution, once agreed upon,
various strategies are shared and explained by the students.
Students will make sense of mathematics, develop efficient
computation strategies, communicate mathematically, to reason and
prove solutions.
Slide 3
Links to Common Core Instructional Shifts The Shifts in Math 1.
Focus strongly where the Standards focus. 2. Coherence: Think
across grades, and link to major topics within grades. 3. Rigor: In
major topics pursue conceptual understanding, procedural skill and
fluency, and application with equity intensity. Number talks school
wide addresses these shifts. Number talks also address many of the
standards for mathematical practices.
Slide 4
Links to Common Core Instructional Shifts Mathematical
practices are eight overarching standards that thread through all
the grade levels and are not content specific but more related to
mathematical habits. Number talks address many of these standards
for mathematical practices. 1 Make sense of problems and persevere
in solving them. 2 Reason abstractly and quantitatively. 3
Construct viable arguments and critique the reasoning of others. 6
Attend to precision. 7 Look for and make use of structure. 8 Look
for and express regularity in repeated reasoning.
Slide 5
Impact on Students Quotes from Mr. Jacobsmeyers Mar Vista
2012-2013 6 th grade class: It gave me a new way or a better way of
approaching problems by not using the algorithm. If you listened to
your classmates explain their method, them you could get more ideas
for other problems. Say someone has a cool method, you could take
various approaches to make you own method. Learning other methods
and learning how others think, I can use strategies to solve more
complex problems through breaking them down.

Slide 7
Tips on Implementation (Lessons Learned) Tips for Teachers:
Your are not teaching in the traditional sense, its more of a
Socratic process. Students are discovering and you are guiding them
through questions. Take time to build in the routine and structure.
Give the process some time and intended results will follow Tips
for Administrators: Transition- go slow to go fast Will not look
like a traditional math class. Support/materials (see following
