FOLSOM CORDOVA UNIFIED SCHOOL DISTRICT INTEGRATED MATH 2 FOUNDATIONS (10) Date: April 2016 Proposed Grade Level(s): 10-12 Grading: A-F Course Length: 1 year Subject Area: 1 year Credits: 5 per semester Articulation Units: N/A Prerequisite(s): IEP Team Recommendation Intent to Pursue βA-Gβ College Prep Status: No COURSE DESCRIPTION: This is a non-college preparatory course, structured around problems and investigations that build spatial visualization skills, conceptual understanding of geometry topics, the algebra 1 topics not covered in Integrated Math 1or Integrated Math 1(10), introductory statistical analysis, and an awareness of connections between different ideas. The slower pace and reduced student to teacher ratio allows time to address individual IEP (Individualized Education Plan) goals. Students are encouraged to investigate and conjecture to develop their reasoning skills. Lessons are structured for students to collaborate actively by working collaboratively with peers. The course will focus on the algebra I standards not completed in Integrated Math 1 or Integrated Math 1(10), and develop an understanding of foundational geometry standards that students will learn in Integrated Math 2, without engaging in formal proofs. The big ideas of the course are presented in an integrated algebra/geometry context. Any aspect of this class is subject to accommodations based on IEPs. GENERAL GOALS/ESSENTIAL QUESTIONS: The Integrated Math 2 Foundations (10) course has a focus on quadratic expressions, equations, and functions; comparing their characteristics and behavior to those of linear and exponential relationships from Integrated Math 1 or Integrated Math 1(10). This course also has a focus on geometric concepts that include congruence, similarity, and polygon attributes and theorems. The Integrated Math 2 Foundations (10) course includes standards from the conceptual categories of Number and Quantity, Algebra, Functions, Geometry, and Statistics and Probability. Some standards are repeated in multiple higher mathematics courses, therefore instructional notes, which appear in bold, indicate what is appropriate for study in this particular course. The scope of the IM 2 Foundations (10) course is exploring algebraic and geometric relationships, justification and similarity, probability and introduction to trigonometry, factoring, quadratic functions, transformations and similarity, exploring proof, polygons and circles, and functions. For the Integrated Math 2 Foundations (10) course, instructional time should focus on seven critical areas: (1) extend the laws of exponents to rational exponents; (2) compare key characteristics of quadratic functions with those of linear and exponential functions; (3) create and solve equations and inequalities and graphs involving linear, exponential, and quadratics and (4) establish criteria for similarity of triangles based on dilations and proportional reasoning; (5) polygons and circles; (6) algebraic and geometric relationships, and (7) right triangles. Upon completion of the course, students can move into Integrated Math 2 or Integrated Math 2 (10), with a C or better, or continue on a non-college preparatory path. This course will satisfy the Integrated Math 2 graduation requirement for FCUSD. Page 1 Essential questions include but are not limited to: How is thinking algebraically different from thinking arithmetically? What are some examples of using algebra to solve geometry problems? What are the differences between rational and irrational numbers? How do we approximate irrational numbers? What are the similarities and differences between the images and pre-images generated by translations? What are some real-world examples of quadratic functions? How do you decide the best method to solve a quadratic equation? COMMON CORE STATE STANDARD READING COMPONENT: The major principles of the California Common Core Standards for Mathematics places strong emphasis on focus, coherence, and rigor. Students are to pursue with equal intensity conceptual understanding and procedural skill and fluency, along with application. Students will read high school level math textbook scenarios and real-world math problems to apply mathematical ideas and concepts. Students will read for explicitly stated and/or implied information that will be used to ask questions and to draw conclusions. Students will translate the context of reading material into math symbols, equations, graphs, diagrams, and other mathematical models. The curriculum has literacy strategies embedded within the text that assists students in the following: Understanding math tasks; Communicating their understanding orally and through writing; Writing about math; Building math vocabulary; and Building academic vocabulary. COMMON CORE STATE STANDARD WRITING COMPONENT: Students are to think across grades and link to major topics in each grade. Students will use productive discussion in small and large groups to build conceptual understanding. Through writing, students explain, assert and defend claims. Students will also use written explanations to support mathematical procedures. COMMON CORE STATE STANDARD SPEAKING AND LISTENING COMPONENTS: Students will use productive discussion in small and large groups to build conceptual understanding. Students will engage in productive dialogue to make sense of information from a variety of sources: graphs, tables, diagrams, figures, mathematical models, expressions and equations, and written explanations, to name a few. Speaking and listening protocols for small and large groups will be used to facilitate student success in the process of learning mathematics and will provide students opportunities to share ideas and critique the ideas of others.
