Westside High School Lesson Plan Teacher Name: Garrett, Shannen Unit Name and #: Unit 2: Unit 3: Triangle Properties and Congruence Course: Geometry MOD B Dates: Mar 30 – Apr 3, 2015 What are we learning? Daily Objective: Students will be able to find the measurement of a missing angle by using Triangle Angle Sum Theorem. TEKS/AP/Standards: Monday GEOM.1A Develop an awareness of the structure of a mathematical system, connecting definitions, postulates, logical reasoning, and theorems to verify statements. Ⓡ GEOM.3C Use logical reasoning and several methods of proof (flow proofs, transformation proofs, coordinate proofs, and two-column proofs) to prove statements are true, and find counter- examples to disprove statements that are false. Ⓢ GEOM.3E Use deductive reasoning to prove a statement. How will we learn it? Learning Activities: Triangle Sum Theory Discovery Activity How will we tell if we’re learning it correctly? Assessment Methods: Triangle Sum Theory Discovery Activity Checks for Understanding: Teacher observation One-on-one instruction What do I need to be successful? Materials: Calculators, worksheet, computer, PowerPoint, notes What do I need to do before next class? Follow Up/HW: What are we learning?
