Teacher : Holly Carter | |
Course/ Subject: Pre-Calculus – Verifying Trigonometric Identities | |
Date of Instruction: 10/07/2021 | |
Opening (I Do) An engaging process for lesson introduction that is specifically planned to encourage equitable and purposeful student participation. Describe the instructional process that will be used to introduce the lesson. TKES 1, 2, 3,4,5, 8,10 | Standards: MGSE9-12.F.TF.8 MGSE9-12.F.TF.9 |
Learning Target: I can use the sum and difference formulas to evaluate a trig function. | |
Success Criteria: I can substitute one identity for its equivalent. I can find to angles from the unit circle that add or subtract to give me the value of an angle not on the unit circle. . | |
Introduction/Connection: Do now -SAT/ACT Practice- students will answer multiple choice questions written in the SAT or ACT style – posted in Google Classroom Connection – Find the exact trig value of an angle on the unit circle. | |
DIRECT INSTRUCTION: We will go over homework. I will demonstrate how to verify sum and difference formulas and point out the similarities to problems we have already done. | |
Work Period (We Do, You Do) Students learning by doing/demonstrating learning expectations. Describe the instructional process that will be used to engage the students in the work period. TKES 1, 2, 3, 4, 5, 7. 8,10 | GUIDED PRACTICE: We will work Yellow Book problems on page 490 25-43 odd together. |
INDEPENDENT/COLLABORATIVE PRACTICE/DIFFERENTIATION: Students will practice independently by completing Yellow Book p490 5 – 23 odd | |
Closing (We Check) Describe the instructional process that will be used to close the lesson and check for student understanding. TKES : 1,2,3, 4,5,6,7,8 | SUMMARIZE/CHECK FOR UNDERSTANDING: We will check several of the problems to verify understanding. |
