Learning Task - Constructing understanding through deep/rich contextualized problem solving tasks. Practice Task - Tasks that provide students opportunities to practice skills and concepts. Performance Task - Tasks which may be a formative or summative assessment that checks for student understanding/misunderstanding and or progress toward the standard/learning goals at different points during a unit of instruction. Culminating Task - Designed to require students to use several concepts learned during the unit to answer a new or unique situation. Allows students to give evidence of their own understanding toward the mastery of the standard and requires them to extend their chain of mathematical reasoning. Achieve CCSS- CTE - Designed to demonstrate how the Common Core and Career and Technical Classroom Tasks - Education knowledge and skills can be integrated. The tasks provide teachers with realistic applications that combine mathematics and CTE content. Short Cycle Task - Designed to exemplify the performance targets that the standards imply. The tasks, with the associated guidance, equip teachers to monitor overall progress in their students’ mathematics. Formative Assessment Lesson (FAL) - Lessons that support teachers in formative assessment which both reveal and develop students’ understanding of key mathematical ideas and applications. These lessons enable teachers and students to monitor in more detail their progress towards the targets of the standards. Formative Assessment Lessons (FALs) Formative Assessment Lessons (FALs) • Formative Assessment Lessons (“Classroom Challenges”) • Developed by the Shell Center • Embedded in the FY14 Units, also available at http://map.mathshell.org.uk/materials/lessons.php • Intended to guide instructional decisions for the rest of the unit • Not intended to be graded, but for feedback • Very beneficial to addressing student misconceptions • Additional FALs are in the editing process. Short Cycle Tasks • Also from the Shell Center (Mathematics Assessment Project web site: http://map.mathshell.org.uk/materials/lessons.php) • Go to the “Tasks” tab: Short assessments with rubrics “Mathematical skills and practices might be assessed partly in isolation, partly under scaffolded conditions, and partly when students face substantial problems without scaffolded support. We call tasks that assess these three different types of performance novice, apprentice, and expert tasks respectively” For the FALs click on this tab For the Short Cycle Tasks click on this tab Make sure to choose the Correct grade level Internet Resources • Webinar Information • General Resources • Problem-Based Learning • Assessment and Instructional Support Resources Examples of Resources Unit 2 Exponents and Equations Overall Changes in the Unit Slight change of format Inclusion of Short Cycle Tasks and Formative Assessment Lessons from the Shell Center Included Standards for Mathematical Practices for each Task Suggestions sent by teachers from all over the United States via email and the wiki Observations made from personal experiences Selected Terms and Symbols Note: In the Teacher’s Edition (found in the Learning Village), the Task Table includes hyperlinks to the FALs and Short Cycle Task. The link is also found on the task page within the unit. A new section has been included in each task to list the appropriate Standards for Mathematical Practices (SMPs). The standards are hyperlinked to the CCGPS document which can also be found at www.georgiastandards.org Common Misconceptions have been identified for each task to assist teachers in guiding the students to success. Suggestions for Differentiation have been added to each task. Things to Remember Use the Wiki to share information with other teachers and to ask questions. This is a living document. Please share anything you may have to enhance this or any unit. The Wiki is the teacher community page to share anything you have. The DOE CCGPS tab is static, viewable for anyone. Teacher pages and any updates or additional resources, including hot links, are only available through Learning Village. If you are attending the Georgia Mathematics Conference at Rock Eagle in October, come visit us. Our session is Friday morning.

Nathan Deal announced today that Georgia is withdrawing from the Partnership for Assessment of Readiness for College and Careers (PARCC) test development consortium. Instead, the Georgia Department of Education (GaDOE) will work with educators across the state to create standardized tests aligned to Georgia’s current academic standards in mathematics and English language arts for elementary, middle and high school students. Additionally, Georgia will seek opportunities to collaborate with other states.
