Midterm Study Concepts
Here are the four major study concepts we will focus on for our midterm:
1. Integer Operations
2. Coordinate Plane
3. Simplifying Variable Expressions
4. Solving Equations (all operations)
We will be reviewing all week in class and adding to our study guides. Your best resources for study will be your previous quizzes and tests. Don't forget to practice with ixl - you have completed these concepts online already, but ixl will allow you to go back and re-practice.

Quiz Thursday
Hello! This is just a reminder that your quiz on Thursday will include equations with all operations (adding, subtracting, multiplying, and dividing). Remember that your objective is to isolate the variable, and this is accomplished by performing the opposite operation to both sides. Be sure to look through your notes before your quiz. It will also include integers and absolute value. Tomorrow we will play a review game. Happy studying!

Least Common Multiple
A few reminders for LCM:
A multiple is the product of two numbers. 10 is a multiple of both 2 and 5, for example. Be careful not to confuses multiples with factors.
When finding the LCM using prime factorization, use each match only once, and then bring all the other numbers "down to the party."
If you are finding the LCM of three numbers, your common factors ("matches") do NOT need to be found in all three numbers to be considered a match.
For practice, go to IXL and choose 6th Grade Math > E.8

Ixl link for Adding and Subtracting Equations
https://www.ixl.com/math/grade-7/complete-addition-and-subtraction-equations-with-integers
Remember to do the OPPOSITE operation in order to isolate the variable. Take it slow - remember your integer rules!

Integer Club
Stay tuned for our new board tomorrow. Integer boot camp gets real. So far, shout-outs to Trey, Adrienne, and Olivia for making it to the addition club. Nicely done. We will be working on this all week and possibly into next week. Please review your integer rules every night, even if you do not have homework (answers to correct).

Lulzzzzz
That one time in Pre-Algebra when you guys did an AWESOME job with Order of Operations... and Stone's inner competitor came out like a lion.. and Dylan ended up picking up allll the colored pencils....
Hahaha. Seriously though, today was fun. Keep those PEMDAS skills up.

Welcome Back!!!
WOW, guys! Is it really that time already?! I'm looking forward to seeing some familiar faces and to meeting new ones. It's going to be a great year! Stay tuned for details coming soon regarding how to check this blog for homework assignments, upcoming projects, and fun stuff we'll be doing in class. :) I hope everyone had a wonderful summer and can't wait to catch up with all of you tomorrow!!!

Some Fraction Stuff!
Greetings, Mathlings!
As we move on through Chapter 5, please be sure to refer back to your notes if you run into trouble. Here are a couple good sites that I found that break down the process of adding, subtracting, multiplying and dividing with fractions in a super-simple way. Check 'em out:
Add/subtract - http://www.math.com/school/subject1/lessons/S1U4L3GL.html
Multiply/divide - http://www.math.com/school/subject1/lessons/S1U4L4GL.html
Also, here are a couple of games that are simple, but are a great mind-jog for reviewing things like comparing and ordering fractions with different denominators, etc:

Midterm Study Guide
What to expect:
Concepts from Chapters 1 - 3 (excluding rounding, solving inequalities and the metric system)
Resources to study:
- Previous blog posts
- Khan Academy videos
- Be sure to look back @ all 3 tests we've taken
- Quick Checks in your online textbook
- The Chapter Review @ the end of each chapter (we'll be using these a lot in class)
Things you'll need to know by chapter:
Chp. 1
Variable expressions: Knowing how to express a numerical value using a variable. For example, "twenty-five less than x" would be expressed by x - 25.
Order of Operations: PEMDAS
Evaluating a variable expression: Just substitute the variable. For example, 3x + 4 for x = 5 would look like this, after substituting 5 for x: 3(5) + 4. Then we'd use order of operations: 15 + 4 = 9.
Integers: Everyone's favorite! (hehe just kidding, I think?) Take a look at old blog posts to refresh your memory. There's lots of info on here about how to solve problems with negative numbers.
- Absolute value
- Comparing integers (for example, what's greater, -7 or -9?)
- Adding and subtracting integers
- Multiplying and dividing integers
Number patterns: Figuring out what the "rule" is for a pattern, and then finding the next few numbers. For example, for the set 0, 6, 12, 18... we can conclude that the rule is "start w/ zero and add 6", and that the next two numbers will be 24 and 30.
The coordinate plane: You'll need to know how to graph a set of coordnates, such as (3, 5)
Chp. 2
Distributive Property: Know how to distribute by multiplying what's on the outside of the parentheses to the items inside the parentheses separately. For example, 3(6 + 2) is distributed as 3(6) + 3(2), which gives us 18 + 6 = 24.
Simplifying variable expressions: Remember to:
1) Change any subtracting to adding a negative
2) Combine like terms
For example: To simplify 2x + 3y - 2y + 7, we first rewrite the expression without subtraction:
2x + 3y + -2y + 7
Then, combine like terms:
2x + y + 7
Solving Equations: This is the big one! Remember to do the opposite to both sides in order to get the variable by itself! Check out previous examples in the blog. I think most of you have a pretty good handle on solving equations, but we'll be practicing a lot in class too.
Graphing inequalities
Chp. 3
Measures of Central Tendency: This means mean, median, mode (and range)
Mean: Add 'em all up and then divide by however many numbers you have
Median: Line 'em up in order from least to greatest - then identify the middle number (OR, if there are two middle numbers, the median is the mean of those two middle numbers)
Mode: The number that appears most often
Range: The difference between the greatest and least values in the data set
Formulas: You don't need to memorize any formulas. You just need to be able to plug in the right numbers into a formula. For example, if a rectangle has a length of 5 inches and a width of 2 inches, and the formula for the Area is length x width, you'll need to plug 5 x 2 into the formula and solve (we'd get 10 inches squared).
Solving Equations w/ Decimals: Same exact method for solving equations, only a little more complex because we're using decimals instead of whole numbers.
