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 – complex numbers in standard form

DIRECT INSTRUCTION:

Discuss homework.  Notes and examples on the trigonometric form of a complex number (Power Point) 

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 practice problems that correspond with the notes. Students will be allowed to collaborate to find solutions.

INDEPENDENT/COLLABORATIVE PRACTICE/DIFFERENTIATION:

Complex Numbers in Trigonometric Form worksheet

Scaffolding will be provided throughout the lesson.

Students may work in pairs or independently.

Detailed explanations of problems will be provided for students on Google Classroom.

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:

As students answer questions during the guided practice I will check for understanding by spot checking their work.
