Trousdale County Schools Weekly Lesson Plan Teacher: Canaan Bowman Pacing Guide Week #: 12 Dates: 10/28 – 11/1 4 days Subject: Geometry Common Core Standard(s) to be taught: (Write the entire standard) CCSS G.CO.7 – Use the definition of congruence in terms of rigid motions to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent. CCSS G.CO.8 – Explain how the criteria for triangle congruence (ASA, SAS, and SSS) follow from the definition of congruence in terms of rigid motions. CCSS G.CO.9 – Prove theorems about triangles. Theorems include: measures of interior angles of a triangle sum to 180 degrees; base angles of isosceles triangles are congruent; the segment joining midpoints of two sides of a triangle is parallel to the third side and half the length; the medians of a triangle meet at a point. SPI(s) to be taught: (Write the entire SPI) SPI 3108.1.1 - Give precise mathematical descriptions or definitions of geometric shapes in the plane and space. SPI 3108.4.2 - Define, identify, describe, and/or model plane figures using appropriate mathematical symbols (including collinear and non-collinear points, lines, segments, rays, angles, triangles, quadrilaterals, and other polygons). SPI 3108.4.3 - Identify, describe and/or apply the relationships and theorems involving different types of triangles, quadrilaterals and other polygons. SPI 3108.4.11 - Use basic theorems about similar and congruent triangles to solve problems. SPI 3108.4.12 - Solve problems involving congruence, similarity, proportional reasoning and/or scale factor of two similar figures or solids. Daily practice activity for citing text based evidence in conversation and/or writing: I Can Statements : Student Agenda: I can write about my reasoning to prove that two triangles Posted daily but NOT included in Lesson Plan are congruent. I can prove that two triangles are congruent using triangle congruence theorems. I can prove theorems about isosceles triangles. I can use theorems about isosceles triangles to solve problems that apply algebra. 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 1 1st Block - Intro to Groups - Review triangle congruence theorems - Notes (proof reasons) - Guided/Group practice in synthesizing proofs - Independent Practice/HW (textbook problems from Lesson 4-2 and 4-3) 2nd Block - Intro to Groups - Review Isosceles Triangle Theorems - Review making proofs involving corresponding parts of congruent triangles - Group practice with isosceles triangle theorems and congruent triangles - Independent Practice/HW (textbook problems from Lessons 4-5 and 4-4) Formative Assessment: Student responses when reviewing material covered before break Day 2 CRA Quiz Review if time permits CRA Observations/questioning during whole class guided practice and while students are working within groups Exit Ticket/Homework 1 Day 3 1st Block - Bellringer – Writing Proofs - Quiz (Proofs – Congruent Triangles) - Lesson 4-4 Practice Problems - Group/Independent practice with proving parts of congruent triangles congruent - PLAN Practice 2nd Block - Bellringer – Isosceles Triangles and proofs - Quiz(Proofs/Isosceles Triangles) - Perpendicular Bisector Discovery Lab - PLAN Practice Bellringer – assess for any misconceptions involving problems on quiz Day 4 1st Block - Bellringer – PLAN Practice - Lesson 4-5 Notes/Guided Practice Problems - Review congruent parts of congruent triangles proofs - Group practice with Isosceles Triangle problems and proofs - Independent Practice/HW (from textbook Lessons 4-4 and 4-5) 2nd Block - Bellringer – PLAN Practice - Lesson 4-6 and 4-7 Notes/Guided Practice - Group practice (Using the HL Theorem and Overlapping Triangles) - Independent Practice/HW (from textbook Lessons 4-6 and 4-7) Day 5 1st Block - Bellringer – Quiz prep - Quiz (Proofs/Isosceles Triangles) - Lesson 4-6 Notes/Guided Practice - Group Practice (Using the HL Theorem) - Independent Practice/HW (from textbook Lessons 4-6) - PLAN Practice 2nd Block - Bellringer – Quiz prep - Quiz (HL Theorem and Overlapping Triangles) - Chapter 4 Review (p. 273-276) - PLAN Practice Bellringer Quiz (Proofs/Isosceles Triangles) Observations/questioning during group work/lab activity(what are students able to discover on their own) Observations/questioning during whole class guided practice and while students are working in groups Exit Ticket Bellringer – assess for any misconceptions involving problems on quiz Quiz Observations/questioning during whole class guided practice and while students are working in groups Day 6 Day 7 Alternate Instructional Interventions: Provide a specific plan for alternate instructional interventions, or re-teaching. On B days, the end of class will be used to re-address any material with which students show difficulty in understanding. Students will be allowed to re-take quizzes that they scored poorly on using InteractMath to improve their grade and gain more exposure to the content. Instructional technologies to enhance learning: List how each will enhance the effectiveness of the lesson. InteractMath website will be used for students to improve quiz grades and gain more exposure to the content in a one-on-one environment while also giving the students more responsibility over their own learning. 2
