3.01 One and
Two-Step Equations
Objective: To solve equations using
the addition and multiplication properties
Narration: Students must show all
of the steps involved in solving one and two-step equations,
working to isolate the variable to one side of the equation

3.02 Equations
with Fractions and Decimals
Objective: To clear an equation of
fractions or decimals
Narration: To simplify the solving
of equations containing fractions, one can multiply both sides
of the equation by the common denominator. To simplify
equations containing decimals, multiply both sides of the
equation by 10 in order to move the decimal point over one place
or by 100 in order to move the decimal over two places.
Assignment: Page 140: #13 – 23
3.03 Absolute
Value
Objective: To solve equations
containing absolute value
Narration: First isolate the
absolute value, and then locate the two equations
Assignment: Page 146: 23 – 32
3.04 Proportions
Objective: To solve problems
involving proportions
Narration: When two ratios are set
equal to one another, it creates a proportion. The method used
in this lesson to solve proportions is to multiply both sides of
the equation by the common denominator (the method used in
section 3.03 above)

3.05 Percent
Objective: To solve equations
involving percents
Narration: Percent means
per one hundred. To solve problems involving percent, we
can change the percent to a decimal by moving the decimal to the
left two places. We can solve problems involving percent by
using a proportion or by translating to an equation and
solving. Since problems with fractional percents are more
easily solved by translating to an equation, that method is
recommended here.

3.06 More
Expressions and Equations
Objective: To translate compound
phrases into algebraic expressions, and to solve problems by
writing and solving equations
Narration: When problems contain
more than one variable, first decide which unknown quantity the
variable will represent and then express the other unknown
quantities in terms of that variable.

3.07 At the Movies
Objective: To solve a word problem
using proportions
At the Movies
It is now 7:51 p.m. The movie that you
have waited three weeks to see starts at 8:15 p.m. Standing in
line for the movie, you count 146 people ahead of you. Nine
people can buy their tickets in 70 seconds. Will you be able to
buy your ticket before the movie starts?
Show your calculations and explain your
solution.
Email your answer to your teacher.
3.08 SET
Objective: To develop reasoning
skills
Narration: The more frequently you
play this game, the faster you will develop your mathematical
reasoning skills!
Assignment: Continue to play the
game of SET at least twice per week. Continue to record your
time on your Excel spreadsheet and email it to your teacher each
week.
3.09 Self Test
Objective: For you to complete the self
test with a perfect score.
