CLARKSTON HIGH SCHOOL - LESSON PLAN: Mathematics Teacher: Golding Course: Math 2 Week of: 10-05 to 10-08, 2009 Blocks: 2nd and 4th The teacher reserves the right to alter these plans in an effort to meet the needs of the students Targeted Standard: MM2G1 & MM2G2 Vocabulary: , right triangle, similar triangles, opposite side, adjacent side Terminology: TSW = Today Students will; TTW = Today Teacher Will; EOCT = End of Course Test; GPS = Georgia Performance Standards, IWB = interactive white board Technology: Calculator, PC Projector, Elmo, Video I – METHODS Lecture M T W H F Date: 10.05 GPS: MM2G2b Demonstration Topics: trig functions and complementary angles Discuss / Questions Essential Question: How are the trigonometric functions related for complementary angles? Audio-visual Cooperative Groups Objective(s): You will describe the relationship between the trig ratios for complementary angles. Class work Independent Study Home work Opening Sponge – (10 min) What are the two unknown lengths in this triangle (given angle is 5° and opposite side is 10 feet). (Solution: hypotenuse = 114.74 feet and adjacent = 114.30 feet) Mini Lesson – (10 min) Trig functions for complementary angles (sinx = cos(90-x)). Work Period: (65 min): You will: 1. Solve sine and cosine problems for complementary angles. (Golding) 2. Solve sine, cosine, and tangent problems for all angles 0-90°. (McCrae) Closing (5 minutes): Reading in Content: Student Exploration Homework: Monday Materials: calculators Modifications: Extra time: Preferential seating: Shortened assignments: Small Group: Other: Other: II – MATERIALS Text Date: 10.06 Audio-visual Aid Overhead Transparencies GPS: MM2G2a,b,c Topics: trig functions and complementary angles Opening Sponge – (10 min) Warmup quiz. 2 questions. A ladder leaning against a building & stairs. See SMART Notebook for pictures and problems. Essential Question: How are the trigonometric functions related for complementary angles? Mini Lesson – (10 min) Set expectations for the work period. Students will divide into the same two groups as yesterday and visit the other teacher’s station. Objective(s): You will describe the relationship between the trig ratios for complementary angles. Work Period: (65 min): You will visit a station you’ve not already been to: 1. Complementary angles in right triangles (Golding) 2. Trig function practice (McCrae) Reading in Content: Closing (5 minutes): Materials: calculators Homework: p. 169 #12 & 19 Chalk/White board Modifications: Extra time: Preferential seating: Shortened assignments: Small Group: Tuesday Library Ref. Mat. Graph/Chart Date: 10.07 Puzzle/Cartoon GPS: MM2G2c Opening Sponge – (10 min) Topics: inverse trig functions Mini Lesson – (10 min) We will teach you the inverse trig functions so you can compute an angle given Essential Question: How do I use trig functions to two sides of a right triangle. compute an angle if I already know 2 sides in a right triangle? Work Period: (65 min): You will complete and submit for grading as a task – the Coca-Cola Right Triangles Task. Objective(s): You will apply the inverse trig 1. Measure 2 sides of the triangle with a ruler. functions to solving right triangles. 2. Sketch and label your triangle, including the number on the face of the triangle. 3. Set up the appropriate inverse trig function. Reading in Content: Coca-Cola Right Triangles 4. Solve the appropriate inverse trig function. Task 5. Repeat steps 1-4 for all 10 Coca-Cola triangles. You should complete this task on notebook paper. Recall that the task rubric Materials: rulers, Coca-Cola right triangles, protractors Closing (5 minutes): Lab Material Other: Worksheet Other: EOCT or GHSGT III – EVALUATION Oral Responses Questions Notebook Check Wednesday Homework: p. 175 #15-22 OR #23 Modifications: Extra time: Preferential seating: Shortened assignments: Small Group: Homework Date: 10.08 Quiz Major Test Project/Paper GPS: MM2G1 & MM2G2 Topics: right triangle support day Opening Sponge – (10 min) What time of day was this photo of the Washington Monument taken? (See SMART Notebook for the image and details) Essential Question: Mini Lesson – (10 min) Set expectations for the work period. Objective(s): Reading in Content: Work Period: (65 min): You will: 1. Apply trig functions to find unknown side lengths in application problems. 2. Apply inverse trig functions to find an unknown angle.
