Common Core Aligned Lesson Plan Subject: Geometry Unit: Right Triangles and Trigonometric Relationships Week: 11 Teacher: Mr. Ives Grade: 10-11 Day: 1 Rocinante High School LESSON ELEMENT: Angles of Elevation and Depression STUDENT-FRIENDLY TRANSLATION Common Core Learning Standards Addressed: G-CO.13, G-SRT.05, G-SRT.06 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.07 Explain and use the relationship between the sine and the cosine of complementary angles. G-SRT-.08 Learning Goals and Objectives: (What will students know & be able to do as a result of this lesson?) The students will be able to identify angles of elevation and depression and find missing sides of triangles in real-world problems. I can solve indirect measurement problems. Vocabulary Support: (What vocabulary will student need for this lesson?) right triangle, angle of elevation, angle of depression, trigonometric ratio, sine, cosine, tangent, and indirect measure. I understand the vocabulary of trigonometry. Formative Assessment Criteria for Success: (What does success on this lesson’s outcomes look like?) The student will correctly solve real-world indirect measurement problems involving both angles of elevation and angles of depression. The student will complete the assignment with a rubric of 7 or higher. All notes and diagrams will be complete in their data folder. I will solve real-world indirect measurement problems. Activities/Tasks: (What learning experiences will students engage in?) Focus activity: Name one thing you know about comets! Video of appropriate science and technology (time permitting) Presentation of angles of elevation and depression. Guided practice of angles of elevation and depression. Independent practice of angles of elevation and depression. In class formative assessment (time permitting) Vocabulary graphic organizer (if needed) Student reflection on learning. Resources/Materials: (What texts, digital resources, & materials will be used in this lesson?) A combination of: Agile Mind software and resources Technology / Science / mathematics slideshow Education Youtube videos Glencoe Geometry textbook and resources Glencoe Algebra II textbook and resources Holt Algebra I Textbook and resources Manipulatives and Puzzles Geometric Templates and drawing tools Laptop computer Pencil and paper Data folder and formula sheet Essential Questions: How can I indirectly measure distances and objects in the real world? How does trigonometry help me with indirect measurement problems? Modifications/Accommodations: What curriculum modifications and classroom accommodations will you make for Students with Disabilities in your class? Extended time for completion of assignments or tests. Additional time for reading assignments. Time for repeated drill and review. Small groups. Data folders with study sheets, vocabulary sheets, and other supplemental aids. Visual demonstrations, which include the presentation of material in small steps. Multisensory materials and activities (written, spoken, demonstration, kinesthetic.) Mnemonic devices and aids. Word processor with spell checker and calculator as well as graphing calculator. Assisted note-taking and note-taking guidelines. Credit for participation, effort and attendance as well as completed work. One-to-one teacher contact daily. Assistance with organization and planning as well as organized classroom procedures and materials. Peer / pair tutoring and cooperative learning. Emphasis on success. Seating to reduce distractions. Clearly defined limits and classroom procedures. Cooling off periods and concrete, positive re-enforcement. Does this lesson reflect one of the Common Core shifts in instruction (See: Common Core Shifts EngageNY.org) In addition, please choose ONE question below to respond to after you have taught the lesson OR create your own question and respond to it after you have taught the lesson. 1. How did this lesson support 21st Century Skills? 2. How did this lesson reflect academic rigor? 3. How did this lesson cognitively engage students? 4. How did this lesson engage students in cooperative learning and cooperative learning skills? 5. How effective was the work in this lesson? Common Core Aligned Lesson: Reflection + I used the resource that has the problems, but not the pictures. It's important to have the students draw the pictures and label them correctly. - Watch for students who have difficulty with abstract ability. ∆ This is yet another lesson that I would like to have more time to teach. Another day of practice would definitely help.
