3. Welcome! Thank you for taking the time to join us in this discussion of Unit 2. At the end of today’s session you should have at least 3 takeaways:  the big idea of Unit 2  something to think about…some food for thought  how might I support student problem solving?  what is my conceptual understanding of the material in this unit?  a list of resources and support available for CCGPS mathematics

4. Welcome! Please provide feedback at the end of today’s session.  Feedback helps us become better teachers, and it helps you to reflect upon your learning.  Feedback helps us as we develop the remaining unit-by-unit webinars.  Please visit http://ccgpsmathematics9-10.wikispaces.com/ to share your feedback, ask questions, and share your ideas and resources. If you are wondering what a wiki is, we will discuss this near the end of this session.http://ccgpsmathematics9-10.wikispaces.com/ After reviewing the remaining units, please contact us with content area focus/format suggestions for future webinars.

5. Welcome! For today’s session have you:  read the standards?  read the unit/completed the tasks in the unit?  downloaded and saved the documents from this session? Ask questions and share resources/ideas for the common good.

6. Expectations and clearing up confusion This webinar focuses on CCGPS content specific to Unit 2, Coordinate Algebra and Accelerated Coordinate Algebra/Analytic Geometry A. For information about CCGPS across a single grade span, please access the list of recorded GPB sessions on Georgiastandards.org. For information on the Standards for Mathematical Practice, please access the list of recorded Blackboard sessions from Fall 2011 on GeorgiaStandards.org. CCGPS is taught and assessed from 2012-2013 and beyond. A list of resources will be provided at the end of this webinar and these documents are posted in the 9-10 wiki. http://ccgpsmathematics9-10.wikispaces.com/

7. Expectations and clearing up confusion The intent of this webinar is to bring awareness to:  the types of tasks that are contained within the unit.  your conceptual understanding of the mathematics in this unit.  approaches to the tasks which provide deeper learning situations for your students. We will not be working through each task during this webinar.

12. Strategies to Improve Students’ Mathematical Problem Solving Skills 1.Prepare problems and use them in whole-class instruction. 2.Assist students in monitoring and reflecting on the problem-solving process. 3.Teach students how to use visual representations. 4.Expose students to multiple problem-solving strategies. 5.Help students recognize and articulate mathematical concepts and notation. What Works Clearing House http://ies.ed.gov/ncee/wwc/PracticeGuide.aspx?sid=16

13. Visual Representations A major task for any student engaged in problem solving is to translate the quantitative information in a problem into a symbolic equation (an arithmetic/algebraic statement) necessary for solving the problem. Students who learn to visually represent the mathematical information in problems prior to writing an equation are more effective at problem solving. What Works Clearing House http://ies.ed.gov/ncee/wwc/PracticeGuide.aspx?sid=16

14. Visual Representations Visual representations help students solve problems by linking the relationships between quantities in the problem with the mathematical operations needed to solve the problem. Visual representations include tables, graphs, number lines, and diagrams such as strip diagrams, percent bars, and schematic diagrams. What Works Clearing House http://ies.ed.gov/ncee/wwc/PracticeGuide.aspx?sid=16

15. Visual Representations Recommendations by WWC to assist students in their development and use of visual representations: Select visual representations that are appropriate for students and the problems they are solving. Use think-alouds and discussions to teach students how to represent problems visually. Show students how to convert the visually represented information into mathematical notation. What Works Clearing House http://ies.ed.gov/ncee/wwc/PracticeGuide.aspx?sid=16

39. Examples & Explanations Fishing Adventures rents small fishing boats to tourists for day long fishing trips. Each boat can hold at most eight people. Additionally, each boat can only carry 1200 pounds of people and gear for safety reasons. Assume on average an adult weighs 150 pounds and a child weighs 75 pounds. Also assume each group will require 200 pounds of gear plus 10 pounds of gear per person. Can a group of 5 adults and 3 children safely rent a boat?

47. Assessment How might it look? Mathematics Assessment Project http://map.mathshell.org/materials/tests.php  The target audience for these example assessments are: 1.teachers who have already started to work on their student’s mathematical practice skills 2.designers of future CCSSM-aligned assessments Illustrative Mathematics - http://illustrativemathematics.org/ http://illustrativemathematics.org/ Online Assessment System - http://www.gadoe.org/Curriculum- Instruction-and-Assessment/Assessment/Pages/OAS.aspx http://www.gadoe.org/Curriculum- Instruction-and-Assessment/Assessment/Pages/OAS.aspx

48. Assessment How might it look?

49. Assessment How might it look? Try thinking about assessment in this way: The chef preparing and tasting the soup in the kitchen is engaged in formative assessment. The person eating the soup in the restaurant is engaged in summative assessment. You are the chef. Adjust constantly with the end in mind.

50. Suggestions for getting started: Read the unit and work through the tasks with your colleagues. What are the big mathematical ideas of the unit? Discuss the focus and coherence of the unit. Discuss where students are going and where students will end up. What do you notice? What do you wonder? What do you need? Share your thoughts and questions on the wiki.
