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

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

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.
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
