Purpose:
Review:
 MA.912.D.7.1
Perform set operations such as union and intersection,
complement, and cross product.
New Concept:
 Prerequisite for MA.912.A

MA.912.A.4.1 (highlight)
Simplify monomials and monomial expressions using the laws of
integral exponents.
FYI: "Integral exponent" means the exponent is a whole number, that
is integer.

Teammates work together to ensure all members
understand; one is randomly selected to be held accountable.
STEPS:
Students number off.
Teacher poses a problem and gives think time.
Students lift up from their chairs to put their heads together,
discuss and teach.
Students sit down when everyone knows the answer or has
something to share.
Teacher calls a number. The student with that number from
each team answers simultaneously, using a small white board.
Teammates celebrate students who responded.
Problem # 1
The set G represents even numbers from 2 to
20.
 G = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
The set P represents multiples of 3 from 3 to
27.
 P = {3, 6, 9, 12, 15, 18, 21, 24, 27}
 How many elements are in the set G ∩ P?
Problem # 1 - Answer

How many elements are in the set G ∩ P?

Problem # 2
The set T represents several Taurine breeds of cattle

T = {Angus, Devon, Shorthorn, Texas Longhorn}
The set Z represents several Zebu breeds of cattle.

Z = {Boran, Nelore, Ponwar}
What is the total number of elements in the set T X Z?
Problem # 2 - Answer

What is the total number of elements in the
se T X Z?
12
Problem # 3
Hint: The symbol ~ represents “not.”
The zip code of a location consists of five digits
chosen from the set Z shown below.
 Z = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
The set L represents the digits in the zip code for Key
Largo.
 L = {3, 3, 0, 3, 7}
The set K represents the digits in the zip code for
Killarney.
 K = {3, 4, 7, 4, 0}
1. How many odd numbers are in the set ~(L ∪ K)?
2. What are the odd numbers left in the set?
Problem # 3 - Answer
How many odd numbers are in the set ~(L ∪ K)?
3
What are the odd numbers left in the set?
{1, 5, 9}
Problem # 4


New Concept: Simplifying Expressions Using
the Product Property of Exponents. Lesson 3

Note Taking:
Product Property of Exponents
If ‘k’ and ‘t’ are real numbers and x is not ‘0’, then
Xk * Xt = Xk+t


35 * 34 = 35+4 = 39
m3 * m2 * m4 * n6 * n7 = m3+2+4 * n6+7= m9 n13
