### Transitioning to the Common Core State Standards – Mathematics1st Grade Session 3

Pam Hutchison

AGENDA

- California Math Framework/ Review Math Practice Standards
- Holiday Word Problems
- Fluency with Addition and Subtraction Facts
- Place Value
- Review the Content Standards

CCSS Mathematical Practices

REASONING AND EXPLAINING

2. Reason abstractly and quantitatively

3. Construct viable arguments are critique the reasoning of

others

OVERARCHING HABITS OF MIND

1. Make sense of problems and perseveres in solving them

6. Attend to precision

MODELING AND USING TOOLS

4. Model with mathematics

5. Use appropriate tools strategically

SEEING STRUCTURE AND GENERALIZING

7. Look for and make use of structure

8. Look for and express regularity in repeated reasoning

Equation Challenge

- Look over the problems on the page. DO NOT begin to solve anything!
- Are there any questions that you want to ask BEFORE you begin to solve the problems?

Equation Challenge

- Work for 60 seconds on your own
- Think about what you know for sure as well as any strategies that might be helpful
- Be ready to share those with your group

Equation Challenge

- SMP #3: Construct viable arguments and critique the reasoning of others”
- Based on your work on Equation Challenge, what are characteristics of a “viable argument”?

Framework

- Look over the framework for Grade 2

Winter #1

At Rudolph’s Holiday Dinner, there were 5 more reindeer than polar bears and 8 fewer polar bears than elves. If there are 10 elves, how many reindeer were at the dinner?

Winter #2

At the park, ¾ of the snowmen were ice skating while the rest were decorating the trees. If there were 9 snowman ice skating, how many were decorating the trees?

Solving and Recording

- Draw to solve (math representation)
- Write a number sentence
- Show your solution

Addition and Subtraction Facts

- Strategies
- Counting all
- Counting on, Counting back
- Decomposing/Composing Strategies
- Doubles, Doubles plus one
- Making fives
- Making tens

SMP#3

- http://insidemathematics.org/index.php/standard-3
- 1st grade lesson
- www.insidemathematics.org

Strategies for Place Value

- Count out 34 cubes
- Now arrange them
- Groups of 10
- Leftovers

Strategies for Place Value

- In just a minute, you are going to count out 51 cubes and arrange them into groups of tens and ones
- How many groups of ten do you think you will be able to make?
- How many ones will be leftover?

Popsicle Stick Numbers

- Student 1 picked “5”and then “tens”
- Student 2 picked “7” and then “ones”
- What number has 5 tens and 7 ones?

Popsicle Stick Numbers

- Student 1 picked “3”and then “ones”
- Student 2 picked “8” and then “tens”
- What number has 3 ones and 8 tens?

Place Value

- What are some additional strategies to promote place value?

Stoplight the Standards

Work in grade level groups to compare

- Common Core State Standards
- Former California Standards

Stoplight the Standards

- As you read each CCSS, find the former CA standard(s) that relate to that CCSS standard

Stoplight the Standards

Look at the standards that are not on the poster

- What are the topics/skills that you can stop teaching right now?

Stoplight the Standards

As you read each CCSS, compare it to the former CA standard(s)

- Highlight in green the CC standard or parts of the standard that are the same as the prior standards
- Highlight in yellow the CC standard or parts of the standard that are similar to the previous standards (some changes)
- Highlight in pink the CC standards or parts of standards that are NOT the same

Stoplight the Standards

Look at the standards highlighted in yellow

- What are the topics/skills that you can stop teaching now?
- What are the topics/skills that you need to find additional materials or lessons to teach?
