Name: Andrea Sisk Date: 12-15-14 WOODLAND HILLS SECONDARY LESSON PLANS Content Area: Geometry Length of Lesson: 14 days STAGE I – DESIRED RESULTS Lesson Topic (Modules, if applicable): Relationships in Triangles Big Ideas: CC.2.3.HS.A.3 Verify and apply geometric theorems asthey relate to geometric figures. Understanding Goals (Concepts): Bisectors, medians and altitudes; Properties of inequalities relating to the measure of angles and sides of a triangle and their applications Student Objectives (Competencies/Outcomes): 1) Identify and use perpendicular bisectors and angle bisectors in triangles 2) Identify and use medians and altitudes in triangles 3) Recognize and apply properties of inequalities to the measures of angles of a triangle 4) Recognize and apply properties of inequalities to the relationships between angles and sides of a triangle. 5) Apply the Triangle Inequality Theorem Essential Questions: Can you…? *Identify and use perpendicular bisectors and angle bisectors in triangles? *Identify and use medians and altitudes in triangles? *Recognize and apply properties of inequalities to the measures of angles and sides of a triangle? *Apply the triangle inequality theorem? *Determine the shortest distance between a point and a line? Vocabulary: Perpendicular bisector, concurrent lines, point of concurrency, circumcenter, incenter, median, centroid, altitude, orthocenter. STAGE II – ASSESSMENT EVIDENCE Performance Task: Formative Assessments: Students will actively participate in mini-lessons, guided and independent Pre-assessments, open-ended higher-order-thinking questions, think-pairpractice, activities (including authentic problem-solving tasks and vocabulary), share, graphic organizers, do nows, observation of guided and independent and group work. Also, students will demonstrate adequate understanding via practice, brief in-class writing prompts various quizzes, a writing assignment, and an end-of-chapter test. STAGE III – LEARNING PLAN Interventions: Flexible grouping, students will be encouraged to attend Math Lab and College and Career Access Center tutoring.
