Represent and/or use numbers in equivalent forms (e.g., integers, fractions, decimals, percents, square roots, exponents and scientific notation). M11.A.2.1 Apply ratio and/or proportion in problem-solving situations. M11.A.2.2 Use exponents, roots and/or absolute value to solve problems. M11.B.2.1 Use and/or compare measurements of angles. M11.C.1.2 Recognize and/or apply properties of angles, triangles and quadrilaterals. Use properties of congruence, correspondence and similarity in problem-solving settings involving twoand three- dimensional figures M11.C.1.3 Student Objectives (Competencies/Outcomes): Students will be able to: Understanding Goals (Concepts): M11.C.1.4 Solve problems involving right triangles using the Pythagorean Theorem.

Essential Questions: Vocabulary: How can you use coordinates and algebraic techniques to represent, interpret, and verify geometric relationships? *Terminal side, standard position, positive & negative angles, coterminal, radian, central angle, complementary, supplementary, sector *Unit circle, cosecant, secant, cotangent, trigonometric functions, domain and period/periodic, even and odd trigonometric functions *Trigonometric identities, Pythagorean Identities, Reciprocal Identities, Quotient Identities *Reference angle STAGE II – ASSESSMENT EVIDENCE Performance Task: Formative Assessments: Students will demonstrate adequate understanding via a chapter test. Pre-assessments, open-ended questions, Think-Pair-Share STAGE III – LEARNING PLAN Interventions: Flexible grouping, students will be encouraged to attend Trig Lab Materials and Resources: Textbook, notes Assignments Procedures Instructional Procedures*: Monday Date: 3/16 Day: B “Do Now” – Graph a sine function that includes a horizontal stretch, and describe why it stretched. “Mini Lesson” – Graphs of Sine and Cosine Functions Students will work on graphs of sine and cosine in which translations are applied. They will discover what causes these particular shifts, both horizontally and vertically. Textbook – Page 410 #37-39, 41, 49, 51, 15-21 odd, 35, 36, 55, 57, 59 Tuesday 3/17 Day: A “Do Now” – Sketch the graph of a cosine function that includes a horizontal and vertical shift. “Mini Lesson” – Graphs of Sine and Cosine Functions Students will work on finding a trig model to describe a set of data, and use this model to answer questions. Students will also find equations for given graphs. Textbook – Page 410 #83, 85, 69-75 odd Wednesday 3/18 Day: B “Do Now” – Given a curve, write equation to match the sketch. “Mini Lesson” – Graphs of Sine and Cosine Functions Students will work on an in-class assignment to continue studying the graphs of sine and cosine. Complete in-class assignment.
