Hello all. Here's a quick rundown of the concepts you'll need to review for your final. Remember, we'll be taking a practice final next week in class as we review, so you'll know exactly what type of problems to expect on the real final.
Stuff you need to know:
- Integer operations (adding, subtracting, multiplying, dividing w/integers) - ***You will not be able to use a calculator for this portion of the test***
- Writing/evaluating expressions
- Simplifying variable expressions
- Solving one-step equations (some of your equations will include decimals or fractions)
- GCF and LCM using Prime Factorization
- Mean, median, mode, range
- Exponent rules/simplifying expressions with exponents
- Scientific notation (everyone's favorite! :)
- Comparing and ordering fractions/decimals
- Proportions, similar figures, probability

3rd Quarter Extra Credit Option
Create a blog post for next year's Pre-Algebra class focusing on one concept from Chapter 5. (For example, multiplying fractions.)
Your blog post must:
1. Teach students how to perform the particular math operation you're focusing on
2. Include both words and graphics
You can send this to me digitally or hand me a hard copy.
Due date: Friday, 3/28
This extra credit assignment will be worth one homework grade (it will take the place of a homework assignment if you've missed one) or three points added to your lowest test/quiz grade.

Hey guys. Sorry I can't be there today. Let's pick up where we left off in our (so-far) review of Chapter 5:
pgs. 283-285, #s 8-40.
Remember, we take math notes for a reason!!! Look back through if you get stuck. If you still can't figure it out, skip it and hopefully when we go over the answers on Friday, you'll remember. :) This is not homework if you don't finish. Not on a show night. However, if you do finish in class, please ask your sub politely if you may play CoolMathGames.com. Your other option is to read - don't forget about all the new books on my shelf.
Good luck tonight - first show night!!! Squeeee! Can't wait to hear all about it!

Funky Fractions
Greetings, Mathlings!
Just some review for what we've already learned for adding and subtracting fractions:
When the fractions have the same denominator, simply add or subtract the numerators, keep the denominator the same, and then simplify.
When the fractions have unlike denominators:
1. Find the Least Common Denominator (The LCM of the denominators)
2. Convert to equivalent fractions - "rename" the fractions with the LCD
3. Follow the procedure for adding/subtracting with the same denominator
Remember, we must find the LCD and rename all the fractions when comparing fractions as well.
....but here's a little something extra for you:
The following chart illustrates the "Butterfly Method" we're going to talk about in class today. A lot of people find it easy to use when you're adding or subtracting with two fractions. *Don't forget to simplify!*

Hey guys! Happy Wednesday!
Here's the link to the fractions game we played today, in case anyone's interested in playing at home:
http://www.math-play.com/adding-and-subtracting-fractions-game.html
Seems like everyone's gotten the hang of fractions so far. Please be sure to finish today's classwork (p.255, 5-17) and then check your answers (listed below). Remember to bring your assignment to class tomorrow ready with any questions you have.

First I'd like to thank you all for doing a wonderful job reviewing for our Cumulative Assessment. You guys did great with reviewing and study time and I enjoyed playing Around The World! Onward to Chapter 5!
Many of you know how to compare and order fractions already. Chapter 5 begins with this very topic - but before we review comparing and ordering fractions, we must master finding the Least Common Multiple (or LCM) or two or more numbers.
Please watch the following video and pay special attention to the Prime Factorization method of finding the LCM:
http://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-factors-and-multiples/cc-6th-lcm/v/least-common-multiple--lcm
Then complete pg. 239, #s 5-13. Try to use the Prime Factorization method for at least three of these problems. See you tomorrow!

Answers to p.228
Howdy guys. Please check your answers to our classwork assignment today so we can workshop with fractions first thing tomorrow. Don't forget to bundle up and stay warm!!! (p.s., that last one - #44 - the "b" kinda looks like a 6, but the answer is "4b")
