DCSD K-12 Mathematics Initiative

Your Menu to Math Success!!

Greetings Wonderful Math Teachers!

Please take the time to read the text and watch the videos. It is imperative that you know and understand the DCSD Math Initiative as it is directly related to classroom instruction and student achievement. I am requesting that you sign the Google form at the end of this newsletter so that I may have proof of your compliance. Thank you!!

...Mistakes are RESPECTED, EXPECTED, and INSPECTED

"True INSTRUCTIONAL RIGOR is "creating an environment in which each student is expected to learn at high levels, each student is expected to learn at high levels, each student is supported so he or she can learn at high levels, ad each student demonstrates learning at high levels (Blackburn, 2012)."


Rigorous and Relevant Lessons - Answers the listed student questions...

What am I learning?

Why am I learning it?

How will I apply/use it?

Mathematics Process

  • originated from PDCA: Plan-DO-Check-Act
  • PDCA is a cyclical method for continuous improvement of processes
  • DCSD: PLAN - ENGAGE - ASSESS
  • We are continuously asking, "What are we trying to accomplish?"; "How will we know that a change is an improvement?"; and "What changes can we make that will result in improvement?"

Mathematics Design

The mathematics design is how your classroom routines are to be constructed to promote maximum student growth and success.

Concrete-Representational-Abstract (C-R-A)

  • C-R-A are the fundamental stages to development content mastery.
  • Instruction includes deep conceptual understanding and procedural fluency. Initial teaching can either be explicit instruction or student exploration that leads to conceptual understanding.
  • Mathematical vocabulary is developed throughout the lesson.
Concrete - Representational - Abstract

Multiple Representation

In mathematics, we represent mathematics solutions in four main ways


  • Verbally
  • Algebraically
  • Numerically
  • Graphically


Students should be able to represent a problem in all four ways, fluidly.

Number Talks

A Number Talk is a short, ongoing daily routine that provides students with meaningful ongoing practice with computation. A Number Talk is a powerful tool for helping students develop computational fluency because the expectation is that they will use number relationships and the structures of numbers to add, subtract, multiply and divide.


Number Talks should be structured as short sessions alongside (but not necessarily directly related to) the ongoing math curriculum. It is important to keep Number Talks short, as they are not intended to replace current curriculum or take up the majority of the time spent on mathematics. In fact, teachers need to spend only 5 to 15 minutes on Number Talks. Number Talks are most effective when done every day.


The primary goal of Number Talks is computational fluency.


The National Council for Teachers of Mathematics states that "Computational fluency refers to having efficient and accurate methods for computing. Students exhibit computational fluency when they demonstrate flexibility in the computational methods they choose, understand and can explain these methods, and produce accurate answers efficiently. The computational methods that a student uses should be based on mathematical ideas that the student understands well, including the structure of the base-ten number system, properties of multiplication and division, and number relationships.” Principal and Standards for School Mathematics, NCTM, Reston, VA 2000, p.152

Number Talks with High School Geometry Students

Math Talks

Math Talk provides students an opportunity for deeper understanding through communication. Individually or in groups, students articulate and defend their ideas and analyze the reasoning of others.

Teachers will gain the ability to assess student knowledge through asking “good questions,” and align instruction to ensure each student understands how to use math skills through thinking, talking, and doing.

Five Major Reasons That Talk Is Critical to Teaching and Learning

  1. Talk can reveal understanding and misunderstanding.
  2. Talk supports robust learning by boosting memory.
  3. Talk supports deeper reasoning.
  4. Talk supports language development.
  5. Talk supports development of social skills.

Using communication in the classroom to represent, explain, justify, agree, and disagree shapes the way students learn mathematics. Classroom dialogue engages students, encourages them to learn more, and allows for the exploration of ideas, strategies, procedures, facts, and more.

Affecting the way ideas are exchanged and developed, Math Talk supports a social learning environment for children—creating a community of encouragement, respect, and the exchange of ideas.

Polya's Problem Solving Process

In 1945, George Polya published a book, "How to Solve It". In this book , Polya identifies four basic principles of problems solving.

Constructing a Response in Math with Close Reading

Close Reading

A strategy that allows readers to dig deeper into a text by:

  1. Reading and re-reading the text to gather meaning and determine purpose
  2. Highlighting important vocabulary words and other essential details that help to determine purpose and meaning.
  3. Providing evidence and support for answers to comprehension questions by using the information from the text.
