Pre-Calculus - Simplifying Trig Expressions

Teacher : Holly Carter

Course/ Subject: Pre-Calculus – Trigonometric Identities

Date of Instruction:  9/15/22

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 one trigonometric function to find the value of the remaining trig functions by using the trigonometric identities.

I can simplify trigonometric expressions.

Success Criteria:

I can identify the quadrant where the terminal side of the angle lies.

I can use the Pythagorean Identities to find another identity.

I can substitute one trig function for its equivalent function.

Introduction/Connection: 

Do now  -SAT/ACT Practice- students will answer multiple choice questions written in the SAT or ACT style – posted in Google Classroom

We will connect the Pythagorean Theorem to the identities.

DIRECT INSTRUCTION:

 We will be practicing finding the value of a trig function and simplifying trigonometric identities.

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 be practicing finding the value of a trig function and simplifying trigonometric identities.  Students will complete simplifying expressions worksheet and Find the value of a trig function worksheet.  We will work together on part of the assignment and students will complete the assignment independently.

INDEPENDENT/COLLABORATIVE PRACTICE/DIFFERENTIATION:

Students will complete the assignments.

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 our example problems to verify understanding.
