LONG DIVISION LESSON
01/09
In middle school math and beyond, you need to understand how to do traditional long division.
WHY?
Because we start to work more and more with decimals from here on out, and you cannot get a decimal answer using partial quotient division.
So... being able to do long division correctly is an essential skill that you need to master.
I created a short video on the basics of long division - the first example gives you a whole number answer, and the second example gives you a decimal number answer.

STEP 1: Please watch the LONG DIVISION VIDEO above.
STEP 2: Complete at least 3 problems on LONG DIVISION PRACTICE (all whole number answers).
STEP 3: If you need more help with dividing and getting decimal answers, go to THIS PAGE.
STEP 4: Complete at least 3 problems on LONG DIVISION WITH DECIMAL ANSWERS PRACTICE.
STEP 5: If you need more help, see this LONG DIVISION LESSON from Cool Math, which includes more practice as well if you need it, OR refer to the Math Notes on page 170 in your math text book.

ADDING and SUBTRACTING
MIXED NUMBERS
01/16
STEP 1: Watch the short video below on Adding and Subtracting Mixed Numbers.
STEP 2: Go to this website to practice this new skill. Use a pencil and paper to work out the problems before entering them in! This site also shows how to add and subtract mixed numbers by first converting them into improper fractions, so if you are more comfortable using that method, feel free to use it.
STEP 3: This website is another resource that explains the step-by-step process that I used in the video. It also covers what to do if you need to "borrow" when subtracting fractions, so please take a look at all of the steps by clicking the Steps 1 - 4 links at the top. There are more practice problems in Step 4 for you to utilize if you'd like!
EXTRA RESOURCE: Your text book goes through this lesson on page 182, so use this for help if you need it.
Khan Academy is also a great resource for practice problems and videos if you get stuck. The practice problems are a little tougher, so if you are up for a challenge, click HERE!

Helpful "Cheat Sheet"
03/17
This PDF was handed out in class and shared with students via school Google accounts. I thought it would be helpful to both students and parents as a tool when completing homework or studying. If you need another copy, feel free to download and print. All material was taken from the "Math Notes" pages in our CPM Core Connections 1 textbook. Hope this helps!
Topics include:
Topics include:
- Multiplying Decimals
- Order of Operations
- Adding and Subtracting Mixed Numbers
- Multiplying Fractions and Mixed Numbers
- Ratios
- Parallelogram Vocabulary
- Base and Height of a Rectangle
- Area of a Parallelogram, Triangle, and Trapezoid
Unit Cost
03/25
We defined unit cost as how much a single item's price is.
We did an example in class that if you bought a set of tires for your car for $435.00, how much did each tire cost? So we divided $435.00 by 4 (since there are 4 tires on a car) to get $108.75 per tire. (See the first worksheet we did in class on Tuesday and Wednesday for these and more examples)
So when finding unit cost, we want to take the total cost/# of items (where the fraction bar means to divide)
in order to find the cost per one item, or cost/1 item (where the fraction bar means "per")
The videos below do a nice, concise job of reviewing the concepts of unit price and then of finding the "better buy":

Using Algebra Tiles to Write Algebraic Expressions
05/20
We have been working on using algebra tiles to write variable expressions and represent unknown quantities. Algebra tiles are a set of manipulatives that are named for their area. Here is a website explaining algebra tiles: Working With Algebra Tiles
This link explains how our CPM book teaches us to write algebraic and variable expressions using algebra tiles:
