Curriculum and Instruction – Office of Mathematics 4th Quarter Algebra II Introduction In 2014, the Shelby County Schools Board of Education adopted a set of ambitious, yet attainable goals for school and student performance. The District is committed to these goals, as further described in our strategic plan, Destination2025. By 2025, 80% of our students will graduate from high school college or career ready 90% of students will graduate on time 100% of our students who graduate college or career ready will enroll in a post-secondary opportunity In order to achieve these ambitious goals, we must collectively work to provide our students with high quality, College and Career Ready standardsaligned instruction. The Tennessee State Standards provide a common set of expectations for what students will know and be able to do at the end of a grade. College and Career Ready Standards are rooted in the knowledge and skills students need to succeed in post-secondary study or careers. The TN State Standards represent three fundamental shifts in mathematics instruction: focus, coherence and rigor. Focus • • • • The Standards call for a greater focus in mathematics. Rather than racing to cover topics in a mile-wide, inch-deep curriculum, the Standards require us to significantly narrow and deepen the way time and energy is spent in the math classroom. We focus deeply on the major work of each grade so that students can gain strong foundations: solid conceptual understanding, a high degree of procedural skill and fluency, and the ability to apply the math they know to solve problems inside and outside the math classroom. For algebra 2, the major clusters, account for 65% of time spent on instruction. Supporting Content - information that supports the understanding and implementation of the major work of the grade. Additional Content - content that does not explicitly connect to the major work of the grade yet it is required for proficiency. Major Content Supporting Content Coherence Rigor Thinking across grades: • The Standards are designed around coherent progressions from grade to grade. Learning is carefully connected across grades so that students can build new understanding onto foundations built in previous years. Each standard is not a new event, but an extension of previous learning. Conceptual understanding: • The Standards call for conceptual understanding of key concepts, such as place value and ratios. Students must be able to access concepts from a number of perspectives so that they are able to see math as more than a set of mnemonics or discrete procedures. • Procedural skill and fluency: • The Standards call for speed and accuracy in calculation. While the high school standards for math do not list high school fluencies, there are suggested fluency standards for algebra 1, geometry and algebra 2. Linking to major topics: • Instead of allowing additional or supporting topics to detract from course, these concepts serve the course focus. For example, instead of data displays as an end in themselves, they are an opportunity to do grade-level word problems. Additional Content Application: • The Standards call for students to use math flexibly for applications in problem-solving contexts. In content areas outside of math, particularly science, students are given the opportunity to use math to make meaning of and access content. Shelby County Schools 2015/2016 3-10-16 1 of 12 Curriculum and Instruction – Office of Mathematics 4th Quarter Algebra II Our collective goal is to ensure our students graduate ready for college and career. The Standards for Mathematical Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students. These practices rest on important “processes and proficiencies” with longstanding importance in mathematics education. The first of these are the NCTM process standards of problem solving, reasoning and proof, communication, representation and connections. Problem Solving Connecton Representation Look for and express regularity in repeated reasoning Look for and make use of structure Reasoning and Proof Communication Make sense of problems and persevere in solving them Reason abstractly and quatitatively Mathematical Practices Attend to precision Construct viable arguments and critique the reasoning of others Model with mathematics The second are the strands of mathematical proficiency specified in the National Research Council’s report Adding It Up: adaptive reasoning, strategic competence, conceptual understanding (comprehension of mathematical concepts, operations and relations) procedural fluency (skill in carrying out procedures flexibly, accurately, efficiently and appropriately), and productive disposition (habitual inclination to see mathematics and sensible, useful and worthwhile, coupled with a belief in diligence and one’s own efficacy). Throughout the year, students should continue to develop proficiency with the eight Standards for Mathematical Practice. Use appropriate tools strategically Major Content Supporting Content Additional Content Shelby County Schools 2015/2016 3-10-16 2 of 12 Curriculum and Instruction – Office of Mathematics 4th Quarter Algebra II How to Use the Mathematic Curriculum Maps This curriculum map is designed to help teachers make effective decisions about what mathematical content to teach so that ultimately our students can reach Destination 2025. To reach our collective student achievement goals, we know that teachers must change their instructional practice in alignment with the three College and Career Ready shifts in instruction for Mathematics. We should see these shifts in all classrooms: 1) Focus 2) Coherence 3) Rigor Throughout this curriculum map, you will see resources as well as links to tasks that will support you in ensuring that students are able to reach the demands of the standards in your classroom. In addition to the resources embedded in the map, there are some high-leverage resources around each of the three shifts that teachers should consistently access: The TNCore Mathematics Standards The Tennessee Mathematics Standards: https://www.tn.gov/education/article/mathematicsstandards Teachers can access the Tennessee State standards, which are featured throughout this curriculum map and represent college and career ready learning at each respective grade level. Mathematical Shifts Focus The standards are focused on fewer topics so students can http://achievethecore.org/shifts-mathematics learn more Coherence http://achievethecore.org/shifts-mathematics Topics within a grade are connected to support focus, and learning is built on understandings from previous grades Rigor http://achievethecore.org/shifts-mathematics The standards set expectations for a balanced approach to pursuing conceptual understanding, procedural fluency, and application and modeling Major Content Supporting Content Additional Content Shelby County Schools 2015/2016 3-10-16 3 of 12 Curriculum and Instruction – Office of Mathematics 4th Quarter Algebra II Curriculum Maps: Locate the TDOE Standards in the left column.

Consult your Pearson/Prentice Hall or Glencoe Algebra 2 Teachers’ Edition (TE) and other cited references to map out your week(s) of instruction. Plan your weekly and daily objectives, using the standards' explanations provided in the second column. Best practices tell us that making objectives measureable increases student mastery. Carefully review the web-based resources provided in the 'Content and Tasks' column and use them as you introduce or assess a particular standard or set of standards. The additional resources provided are supplementary and should be used as needed for content support and differentiation. Review the Literacy Connections found in the right column. Make plans to address the content vocabulary, utilizing the suggested literacy strategies, in your instruction. Examine the other standards and skills you will need to address in order to ensure mastery of the indicated standard. Using your Pearson/Prentice Hall or Glencoe TE and other resources cited in the curriculum map, plan your week using the SCS lesson plan template.
