ENGAGE (MAKE CONTENT AND LEARNING RELEVANT TO REAL LIFE AND CONNECT TO
STUDENT INTEREST) You have the option of earning $35.00 a week for your allowance or
earning $1 on Monday, but then doubling the previous days amount for the remaining days of the
week. Which would you choose?
TEACHER WILL:
 Ask students to calculate the answer
to this question: If you called 3
friends after you ate breakfast, 3
more at lunch time and 3 more after
dinner, how many friends have you
called by the end of the day?
 Ask students to T-P-S the meaning
of base and exponent and how to
evaluate expressions involving
exponents.
 Tell students that you “forgot to tell
them that they had already called 6
friends prior to having breakfast.”
How does that change our
expression?
STUDENT WILL:
 T-P-S (Think-Pair-Share) Model the
given question on your white board
to show the total number of friends
called by the end of the day and then
write an expression for it.
 T-P-S the meaning of base and
exponent and how to solve a power.
 T-P-S how can you include the six
friends that you forgot you called into
your model and expression.
