NUMBER TALKS
Supports the idea that……
Math
is not
a set of rules and procedures Math
is
the relationship between numbers and there are many ways to create and build relationships
Factors for Success in Math
•
Accuracy
the ability to produce an accurate answer •
Efficiency
the ability to choose an appropriate strategy •
Flexibility
the ability to use number relationships
What is Number Talks?
• • Number Talks are discussions about a particular problem that has been crafted in such a way that the key foundational ideas of mathematics can be evaluated and demonstrated These talks take about 5-15 minutes and are typically held 3-5 times a week. • These talks allow students to share their thoughts and ideas about math. It can be taught in whole or small groups • This gives you flexibility to meet the varying needs of your students.

Designing a Number Talk Students get a chance to see the relationships and explore them
• • • • “silent thumb” to give students “think time.” no answer is wrong. Students “defend” or “dispute” a strategy. students can agree or disagree with anyone in the class including themselves.
• • • Open ended questions allow the students to clarify and provide additional ideas share his/her thought process seeing that there truly are multiple ways to solve a problem.
The teacher is seen as a guide not the master……..
Students are asked to clarify their own thinking, consider and test strategies, investigate and apply relationships, and learn that making mistakes and taking risks can and does lead to success -Students don’t simply find the solution to a problem and then move on. They are challenged to see how many different ways they can solve the same problem.
THE CLASSROOM ENVIRONMENT AND COMMUNITY IS THE KEY TO SUCCESS.
First, the teacher must shift his/her thinking away from: What answer did you get? to How did you get that answer?
Also, you have to teach your students to keep their comments on task or else your Number Talks will go on forever!
There are a few challenges to implementing Number Talks.
Questions
• How is math currently taught in your classroom?
• What are the strengths/weaknesses in this area?
• What is your philosophy of math? How is your classroom environment structured?
• Do you have an extra 10 minutes in your day that you can devote to math discussions?
• How can you keep students on task during discussions?
Chapter 2 Preparing For Number Talks
•
Procedures and Expectations
• 1- Designated Location • 2- Provide wait time • 3- Accept, respect, and consider all answers • 4- Encourage student communication
Number Talks
Location
• Whole class or small group • Create a cozy intimate place • Promotes conversation
Wait Time
• Promote think time • Silent thumb signal • Wait until everyone is ready • Encourage multiple ways
Number Talks
Discussion Time
• Prompts help students formulate their answers in respect to matter • Accept other peoples perspectives • Be good listeners
l i t s e n
Questions
1- What area will you designate in your classroom for
Number Talks ?
2- What signals will you use to allow for wait time?
3- How will you encourage/ensure all students to participate?
4- How will you scaffold conversations?
5- How will you hold the students accountable for the materials discussed?
Number Talks for Grades K-2
•
There are 4 goals for grades K-2 using Number Talks:
• (1) Developing number sense • (2) Developing fluency with small numbers • (3) Subitizing, • (4) Making tens.
Developing Number Sense
• “
An awareness and understanding about what numbers are, their relationships, their magnitude, the relative effect of operation on numbers( mental math estimation) Fennell and Landis
• Goal of Number Talks is to further student’s development of number sense • Struggling students can not estimate or determine reasonable answers because they have memorized procedures and formulas
What Does Number Talks Look Like in the Classroom
Dot images, rekeneks, five-frames, ten-frames, number lines, and hundred charts……..
• 1- Provide experiences • 2- Connect math to real life • 3- Learn how to anticipate your students thinking • 4- Sections devoted to grade levels
• • •
Number talks focus
numbers - counting, building fluency, developing one-to-one correspondence and conservation of Encouraged to give careful thought to visual and spacial arrangements of geometric models Each example includes instructions, a graphic, and what to discuss with those cutie kinders you are teaching.
Kindergarten
•
GOAL
to provide students with opportunities to build fluency with numbers and develop addition strategies • You will continue to utilize the tools and models of Kinder but you are focusing on the reasoning with numbers • you have pages of graphics, instructions, and talks to use. There is also a list of addition strategies for you to use with your students.

GOAL
to elicit and foster specific computation strategies. You start the year off with small numbers and grow into larger ones as the year goes on.
