What are update webinars? • Update on the work of the 2013 Resource Revision Team ο Overall revisions ο Unit 3 revisions • Addressing areas which teachers have found to be more challenging • Resources 2013 CA Resource Revision Team Coordinate Algebra/Acc CA Comprehensive Course Overview • Located on the 9-12 math section of www.georgiastandards.org • Designed to provide clarification of CCGPS Mathematics Standards • Organized to link together many sources of information pertinent to CCGPS Coordinate Algebra/Accelerated Coordinate Algebra Begin at www.georgiastandards.org Direct Link to Page Select the CCGPS ELA/Math Tab Direct Link to Page Select the Mathematics option under Browse CCGPS Direct Link to Page Select the 9-12 option in the Mathematics section Direct Link to Page Expand the Coordinate Algebra Course Direct Link to Page Select the Comprehensive Course Overview Expande Coordinate Algebra Direct Link to Page Direct Link to Page Table of Contents • Outlines the Major areas of Focus for the Course • Fully Interactive when viewed via internet • Hover over a section and select to access the section quickly Sections of Interest • Flipbook Access: Detailed Information About Each Standard • Unit Descriptions: Overview • Webinar Information • Assessment Resources and Instructional Support Resources • Internet Resources • Curriculum Map Formative Assessment Lessons (FALs) CCGPS Math Wiki Space Purpose of Tasks • Problem-Based-Learning--Check out Dan Meyer, Robert Kaplinksy’s websites • Provide several entry points to the standards. • Teachers should review all tasks in a given unit to determine which tasks would be appropriate for their students. Tasks can be adapted to fit the needs or your classroom. Most standards are covered by various tasks Goals of Unit Revisions • More user-friendly • Provide teachers with task summaries • Give teachers tools necessary to quickly analyze tasks • Provide tasks from different sources Updates to Unit Frameworks TASK TABLE • Outlines the tasks by type, content and standard. • Provides suggested times • Hyperlinks to PDFs and Word Docsv Updates to Unit Frameworks Unit 3 • Tasks primarily address: – Modeling situations with linear or exponential functions – Exploring function notation and transformations – Understanding sequences as functions Modeling Exponential Functions • • • • Having Kittens Multiplying Cells Community Service, Sequences and Functions Paper Folding (from Unit1) Having Kittens • Students explore if cats could realistically have 2000 descendants in a year and a half. Multiplying Cells • Short task • Students chart out cell populations over time. Community Service, Sequences and Functions • Student explore comparisons in making money in a linear and in an exponential model. Function Notation • Talk is Cheap • Building and Comparing Functions • Functioning Well High Functioning—Vertical Translations High Functioning—Even and Odd Functions MARS FAL • Designed by the shell center • Intended as student-driven, teacher-facilitated lessons that build conceptual understanding A look at MARS FAL: Comparing Investments Lesson Plan A look at MARS FAL: Comparing Investments Misconceptions A look at MARS FAL: Comparing Investments Activities A look at MARS FAL: Comparing Investments Student Work Unit 3 Challenges The coordinate plane shows two functions of π₯. π(π₯) is an increasing linear function. π(π₯) is an increasing exponential function. Based on the information, which statement is true for all real values of the domain x ≥ 0? A. B. C. D. π π₯ = π(π₯) for only one value in the domain π(π₯) = π(π₯) for many values in the domain π(π₯) > π(π₯) for all values in the domain π(π₯) < π(π₯) for all values in the domain Unit 3 Challenges MCC9β12.F.LE.3 Observe using graphs and tables that a quantity increasing exponentially eventually exceeds a quantity increasing linearly, quadratically, or (more generally) as a polynomial function.
