Trousdale County Schools Weekly Lesson Plan Teacher: Mrs. Griggs Pacing Guide Week #: 16 Dates: 12-2-13 to 12-6-13 Subject: Geometry Common Core Standard(s) to be taught: (Write the entire standard) G.SRT.5 Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures G.SRT.6 Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles. G.SRT.7 . Explain and use the relationship between the sine and cosine of complementary angles G.SRT.8 Use trigonometric ratios and the Pythagorean Theorem to solve right triangles in applied problems. ★ SPI(s) to be taught: (Write the entire SPI) SPI 3108.4.12Solve problems involving congruence, similarity, proportional reasoning and/or scale factor of two similar figures or solids. SPI 3108.4.15 Determine and use the appropriate trigonometric ratio for a right triangle to solve a contextual problem. Daily practice activity for citing text based evidence in conversation and/or writing: I Can Statements : Student Agenda: Use special properties of triangles Posted daily but NOT included in Lesson Plan Assessment Strategies (for Stage 1 teachers ONLY): Assessment used to determine mastery daily: If a quiz or test is given, include in the Teacher’s Lesson Plan Notebook. Instructional Materials (for Stage 1 teachers ONLY): All instructional materials are to be included in the Teacher’s Lesson Plan Notebook. Instruction: In outline form, describe each day of instruction. Day 1A Bellringer (Algebra Review handout) Review of 8-1 (Pythagorean Theorem and Converse) and 8-2 Special Triangles Guided and Independent Practice Complete history of mathematician ornament Formative Assessment: Teacher observation of note-taking with question and answer. Day 2B Bellringer Guided review and independent textbook/workbook practice Interact math and makeup work Day 3A Bellringer Notes 8-3 and 8-4 including Law of Sines and Cosines Guided review and independent practice Exit ticket Interact math provides for student selfassessment and work of similar problems. Day 4B Bellringer Guided review and independent textbook/workbook practice Interact math and makeup work Day 5A Bellringer Proving triangles similar (notes 7-3 and 9-5 dilations presented using mobi) Guided and independent practice Interact math provides for student selfassessment and work of similar problems Teacher observation of note-taking with question and answer. Teacher observation of note-taking with question and answer. 1 Day 6A Day 7B Alternate Instructional Interventions: Provide a specific plan for alternate instructional interventions, or re-teaching. RTI will be assigned as needed. Instructional technologies to enhance learning: List how each will enhance the effectiveness of the lesson. TI nspire will be used to solve skill-based problems. Interact math will be used for Common core responses. 2
