Number Talks:
A Great Tool to Promote Number Sense in Young Mathematicians
Jessica Garza & Mindy Cantu

What are Number Talks?
Number Talks are mathematical conversations where
students mentally solve computation problems and use
communication to explain the strategy/strategies used to
determine the solution (Figure 1). The purpose of Number
Talks are for students to:
* Explore mathematical relationships (patterns,
composing/decomposing of numbers)
* Engage in mathematics conversations (listen to peers'
strategies, develop academic vocabulary)
* Develop number sense/mathematical reasoning

of finding 28+28
Why Did We Start Number Talks?
We started Number Talks because we wanted to facilitate
conversations within our Mathematician's Workshop
that would allow students to be curious, take risks, make
mistakes, and explore mathematics strategies without the
pressure of "getting it right." We also started Number
Talks because we wanted to deepen our students' number
sense, use of discourse in mathematics, and mathematical
reasoning skills.
How Did We Start Number Talks?
Getting started with Number Talks is fairly simple. All
you need is somewhere to scribe (whiteboard, chart paper,
etc.) (Figure 2) and students who are ready to participate
(Figure 3).

Below are some key steps to getting started with
Number Talks.
Number Talk: Steps for the Teacher
1. Set norms for Number Talks
* Mathematicians listen to each other.
* Mathematicians explain their thinking.
* Mathematicians use hand signals.
* Mathematicians make mistakes.
* Mathematicians take risks.
2. Record the problem or number string horizontally
on chart paper/whiteboard, etc.
3. Ask for student answers and record the answers (no
explanation).
4. Ask students to defend an answer and explain the
strategy used to find the answer.
5. Record the student's strategy and the student's
name
