Talks

Focus

1. Make sense of problems and persevere in solving them6. Attend to Precision

2. Reason abstractly and quantitatively

3. Construct viable argument and critique the reasoning of others

4. Model with mathematics

5. Use appropriate tools strategically.

7. Look for and make use of structure

8. Look for and express regularity in repeated reasoning

WHICH STUDENT WOULD YOU ARGUE HAS THE

MOST COMPLETE UNDERSTANDING OF THE

COMPUTATION 28 + 33 =

Provide a

collaborative forum

for students to:

Invent Strategies

Generalize individual

strategies into personal

algorithms

Build a conceptual bridge

to the standard algorithm

HOW CAN YOU PREPARE FOR

NUMBER TALKS?

1. Select a designated location that allows you to maintain close proximity to your students

2. Provide appropriate wait time for the majority of the students to access the problem

3. Accept, respect, and consider all answers

4. Encourage student communication throughout the number talk

Kinder -2nd

1. Develop number sense

2. Develop fluency with small numbers

3. Subitizing

4. Making tens

Number Talks Goals for Grades 3-5

1. Number Sense2. Place Value3. Fluency4. Properties5. Connecting

mathematical ideas

MAKING CONNECTIONS STRATEGIES

Present the problem(i.e. dot cards, ten frame,

models, written)

Record all students answers in upper right

Use safe hand signals

Ask to hear and record their thinking for every

answer

Allow students to embrace their mistakes and

change their thinking with the help of others

Once the class has agreed on the “correct”

answer, pose the next level of the problem set

So, how do we

engage students

intentionally and strategically?

25+25+25+25+25+25+25+25

25+25=50

50 +50+50+50=200

•Adding 25 eight times

•Multiplying 4*25 and

doubling

•8*20 plus 8*5

25

100

100

(4*25) + (4*25)

I could ask if anyone knows

how much 1 quarter is worth

and then how much 4

quarters made and then

write 4*25=100

• Are you saying that 4*25 was a

friendly number sentence?

• Could we draw an area model for

your thinking?

• Would you like to rethink your

answer?

LET’S PRACTICE

1. Get in grade level groups

2. Count off in your groups 1-4

3. Gather in group number in a quiet

place, read the background page for

your group number lesson

4. Choose any one of the boxes for the

string you will share

5. As a group, fill out the four-square

planning sheet

6. Each group decide how you want to

present your lesson to the remaining

groups
