TKES 1, 2, 3,4,5, 8,10

Standard/s:

MGSE9-12.F.IF.7 Algebra 1 Standards –     Exponential Characteristics

Learning Target:

·         I will identify exponential functions and their characteristics 

Success Criteria:

·         I can identify an exponential function.

o   Graph – curved line

§  Growth

§  Decay

o   Equation – power of “x” or the power of any variable

§  A value (y-intercept or initial value)

§  B value (growth/decay rate or base value)

o   Table – common ratio

·         I can define the following exponential characteristics:

o   Domain, range, x-intercept y-intercept, growth, decay, asymptote

·         I can identify and label the following exponential characteristics given a graph:

o   Domain, range, x-intercept y-intercept, growth, decay, asymptote

Introduction/Connection:

GUIDED PRACTICE: 

As a class, we will complete two sample problems on exponential characteristics on the worksheet.

INDEPENDENT/COLLABORATIVE PRACTICE/DIFFERENTIATION:

Students will finish the worksheet and share answers on the Mimio Interactive board.  

Closing  (We Check)

Describe the instructional process that will be used to close the lesson and check for student understanding .
