6th, 7th and 8th Grade Math
Summer Packet Links
Remember.......Your Summer Packet Grade counts as a test grade
for the 1st 9 Weeks in 6th, 7th and 8th Grades (UL and Algebra I too)!!!!
Junior High Math Assignments
This is helpful information that can be used all year by my students!
Order of Operations:
G 1) Parenthesis or other grouping symbols
E 2) Exponents
MD-left to right 3) Multiplication or division in the order it appears from left to right
AS-left to right 4) Addition or subtraction in the order it appears from left to right
Adding and Subtracting Rational Numbers:
Same sign, add the numbers, -2 - 6 = -8 4 + 5 = 9
Different signs, subtract.
Take the sign of the dominant number, 2 - 6 = -4 -4 + 5= 1
Then you'll be exact.
A line and a line -8 – - 10
Make a plus sign -8 + 10
Multiplying and Dividing Rational Numbers
pos x pos = pos 6 x 8 = 48
pos x neg = neg 6 x -8 = -48 and -6 x 8 = -48
neg x neg = pos -6 x -8 = 48
any number x zero = zero -6 x 0 = 0
pos / pos = pos 10/2 = 5
pos / neg = neg (Also, neg / pos = neg) 10/-2 = -5 and -10/2 = -5
neg / neg = pos -10/-2 = 5
zero / any number = zero 0/7 = 0 0/-4 = 0
any number / zero = there is no answer for this! 7/0 = undefined
Write problems side by side.
Write fractions in improper form.
You DO NOT get common deminators.
Cancel any common factors in the numerators
Before you leave your answer make sure it is
in simpliest form.
Dividing Fractions (KCF - Keep Change Flip)
Dividing fractions, don't ask why
Just flip the second number and multiply.
And before you say goodbye,
Don't forget to simplify.
Adding and Subtracting Fractions
Write the problem verically (up and down)
Get common denominators.
Put dominant number on top.
You do not have to change to improper fractions.
With subtraction you may have to borrow.
Simplify your answer.
