Teacher : Holly Carter | |
Course/ Subject: Pre-Calculus – Double Angle Formulas | |
Date of Instruction: 2/25/22 | |
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 double angle formulas to evaluate a trig function. I can verify double angle formulas. | |
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 – verifying trig | |
DIRECT INSTRUCTION: I will demonstrate how to use the double angle formulas to find a value of a trig function for an angle not on the unit circle. I will demonstrate how to find the value of a trig function when I know information about to an angle that is half as large. | |
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 the double angle worksheet together. |
INDEPENDENT/COLLABORATIVE PRACTICE/DIFFERENTIATION: Students will practice independently by completing Yellow Book P500 1-9 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. |
