Teacher : Megan Paul

Course/ Subject: Algebra 1 Support

Date of Instruction:  March 2^nd, 2023

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

Standard/s:

MGSE9-12. A.CED.2 Algebra 1 Standards –     Exponential Decay Functions 

Learning Target:

·         I will create, analyze, and evaluate exponential decay problems.

Success Criteria:

·         I can identify the exponential decay equation.

o     A value – initial value

o    R value – rate or percent

o    T value - time

·         I can analyze and calculate exponential decay applications.

·         I can identify the following keywords (decrease, depreciate, falling, declining, etc.) for exponential growth applications. 

·         I can identify half-life as exponential decay applications.

o    P value – initial value

o    T value – # of half-lives in a given period of time
