  1. What is OAK 2? Operations and Algebraic Thinking - OA K-2 Math Teacher Leader Meeting November 15, 2011 Beth Schefelker Lee Ann Pruske Connie Laughlin Hank Kepner

  2. Write a story problem Launch On an index card… • Use the numbers 8, 3, and 11 to compose a story problem. • On a separate card write another problem using the same numbers.

  3. Learning Intentions and Success Criteria • We are learning to understand addition and subtraction problem types and the developmental continuum across K-2. • What does it mean for you to be successful at the end of this session? • We will be successful when we able to identify problem types as described in the CCSS.

  4. CCSS-M Grade K-2 Table 1

  5. Exploring the Story Types • Individually use your two problems to find your story types on the table. • At your table share the types of stories you wrote. • As a table group highlight the chart to identify which problems were created. Be ready to share out.

  6. What’s the difference? What questions do you have about the problem types? Turn and talk with your table group to clarify nuances between the different problem types.

  7. Putting Your Chart to Use • Pull a card and read the problem. • As a table group, come to consensus about which problem type is written on the card. • Pass the cards to a new person and repeat until all cards are done. Which problems caused the most discussion?

  8. Connecting to the CMSP Curriculum Guides K, 1, 2 Curriculum Guides (v2 Oct 31, 2011) • Pg 38 - Kindergarten • Pg 14 - First • Pg 11 – Second The expectation in the CCSS is that students will been engaging in these problem types working toward proficiency in all 12 by the end of 2nd grade.

  9. Background in Problem Types Read and highlight CCSS-M Addition and Subtraction Situations Background • What are the expectations across kindergarten, first and second grades? • In what ways are these problem types the building blocks of algebra? Source: K-5 OA Progressions

  10. K-8 Content Domains, CCSSM K-8 Domains

  11. CCSS Domain Progression

  12. Learning Intentions and Success Criteria • We are learning to understand addition and subtraction problem types and the developmental continuum across K-2. • We will be successful when we able to identify problem types as described in the CCSS.

  13. Professional Practice • For December 6th MTL Meeting: Read the Excerpted Mathematics Curriculum Guide to study the OA Standards in grade K, 1, and 2. Highlight important ideas and come prepared to discuss them in December.

  14. Feedback Question • As a leader of self, what does it mean for you to be successful at understanding addition and subtraction situations in K-2?
