Number Talks

WHY?

• Promotes early number sense

• Fosters mental math

• Develops strategies to understand and solve harder math problems

• Increases math vocabulary

• Gets students EXCITED about math

Teacher's Role

• Facilitator of problems

•Write answers and strategies on board

• Plan for day's number talks

• Be sure Number talks only lasts 5-10 minutes ***Set a timer at first

Where do I start?

Using your Number Talks book, start at least one year below your grade level.

Be prepared with all manipulatives.

Be Patient!

Get ready to be AMAZED!

Signals

• "I have an answer":Student places thumb at chest for ONE idea, they will add a finger for each new idea.

• "I have the same answer as......":Student will put their thumb and pinky up and move their hand back and forth pointing their thumb at themselves and their pinky at the person with the same answer.

Classroom Culture

4 Easy Steps to prepare

1. Find a location that allows for close proximity to your students for informal observations and interactions.

2. Provide appropriate WAIT TIME for majority of students to solve the problem.

3. ACCEPT, RESPECT, and CONSIDER all answers.

4. Encourage student communication.

Four Goals for K-2

1. Developing number sense

2. Developing fluency with small numbers

3. Subitizing

4. Making tens

Grades 2-5 Category KEY

Category 1 represents introductory number talks that more readily encourage a specific strategy.

Category 2 talks are crafted for students who are successfully using the selected strategy.

Category 3 provides opportunities for students to use and extend the targeted strategy.

WHAT DOES THE “K” STANDARD CALL FOR?

3. Decompose numbers less than or equal to 10 into pairs in more

than one way, e.g., by using objects or drawings, and record each

decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4

+ 1).

4. For any number from 1 to 9, find the number that makes 10 when

added to the given number, e.g., by using objects or drawings, and

record the answer with a drawing or equation.

5. Fluently add and subtract within 5.

Category 1: Two addends that make a quick ten
