Entering ALL sections of Algebra I in The Middle School
Summer Math Packet
This packet is designed for you to review all of your pre-algebra skills and make sure you
are well prepared for the start of Algebra I or Honors Algebra I in the Middle School this
fall. We anticipate this packet will take about 7 hours to complete.
Please SHOW ALL WORK neatly in the space provided or attached on a separate sheet of
paper. This assignment is due on the first day of class in the fall.
*Please show all of your work as you were required to do during the entire school year.
Remember No Work-No Credit.
We are really looking forward to the upcoming school year and hope you are too!

III. Order of Operations
To evaluate numerical expressions containing more than one operation, use the rules for order of
operations. The rules are often summarized using the expression GEMDAS.

IV. Evaluating Algebraic Expressions
To evaluate algebraic expressions, first replace the variables with their values. Then, use order of
operations to calculate the value of the resulting numerical expression.

V. The Real Number System
The Real number system consists of two main sub-‐groups Rational numbers and Irrational numbers.
The set of rational numbers includes several subsets: natural numbers, whole numbers, and integers.
Real Numbers-‐ any number on the number line.
o Rational Numbers-‐ a number that can be written as the ratio of two integers
(this includes decimals that have a definite end or repeating pattern)
• Examples: 3 7
2, 5, , 2 , 0.253, 0.34 8
• Integers--- positive and negative whole numbers and 0 • Examples: -5, -3, 0, 8, …
Whole Numbers --- the counting numbers from 0 to infinity
• Examples: {0, 1, 2, 3, 4, ….}
Natural Numbers --- the counting numbers from 1 to infinity • Examples: {1, 2, 3, 4, …}
o Irrational Numbers --- Non-terminating, non-repeating decimals
(including , and the square root of any number that is not a perfect square.)
• Examples: 2 , 3, 20, 3.21793156...

VI. The Distributive Property
The Distributive Property states for any number a, b, and c:
a(b + c) = ab + ac or (b + c)a = ba + ca
a(b − c) = ab − ac or (b − c)a = ba – ca

VII. Combining Like Terms
Terms in algebra are numbers, variables or the product of numbers and variables. In algebraic
expressions terms are separated by addition (+) or subtraction (-) symbols. Terms can be combined
using addition and subtraction if they are like terms.
Like terms have the same variables to the same power.
Example of like-‐terms: 5x2
and −6x2
Example of terms that are NOT like-‐terms: 9x2
and 15x
Although both terms have the variable x, they are not being raised to the same power

IX. Writing Algebraic Expressions
In algebraic expressions, letters such as x and w are called variables. A variable represents an
unspecified number or value.

Write an algebraic expression for each verbal expression.
1) Four times a number decreased by twelve
2) Three more than the product of five and a number
3) The quotient of two more than a number and eight
4) Seven less than twice a number

the question.
1) A video store charges a one‐time membership fee of $11.75 plus $1.50 per video rental.
How many videos did Stewart rent if he spends $71.75?
2) Nick is 30 years less than 3 times Ray’s age. If the sum of their ages is 74, how old are each of
the men?
3) Three‐fourths of the student body attended the pep‐rally. If there were 1230 students at the pep
rally, how many students are there in all?
4) Sarah drove 3 hours more than Michael on their trip to Texas. If the trip took 37 hours, how
long did Sarah and Michael each drive?
