Integer Lessons Review
I've collected a few different links to lessons on how to add, subtract, multiply and divide integers. They're all pretty much the same, so try them all and stick with the one you like best. ;-)
- MATHguide's Operations on Integers Lessons
(There is a quiz after each lesson, refresh the page for new quiz questions.)
- Multiplying and Dividing Integers Lesson
(Lots of pictures! Interactive quizzes follow each lesson. Lots more good stuff on integers at the bottom of this long page.)
- Subtracting Integers Powerpoint Lesson
- Dividing Integers Powerpoint Lesson

I suspect you haven't worked your way through ALL the links I've left you recently. Most of them are the same sort of questions you'll have to write on your class tests. Take advantage of that. The best way to practice for a running race is to do a lot of running. The best way to practice for a math test is to take a lot of math tests. ;-)
But, it can get a little boring only taking tests. So, to make it a little more interesting I've put together a list of links to integer games. You'll still have to remember how to add, subtract (we don't really subtract anymore, smart kids like you add the opposite), multiply and divide. Also, don't forget PEDMAS.
Anyway, let's get to the games ....
- Mystery Picture Game
- Math Car Racing (You've done this one before -- it's got integers now!)
- Guess The Number
- Guess The Number (harder)
- Integer Multiplication Game/Quiz
- Integer Division Game/Quiz
- Review All Integer Operations
(Make sure you read The Party in Mathland then try the Practice Exercises at the end.)

The Last 100 ...
I thought this might interest you ... where did the last 100 visitors to your blog come from? (The "unlisted 8" came from Spain.) ;-)

There and Back Again
This time I've got some quizzes that take us all the way back to multiplication, factors and fractions and then back to where we are now; integers.
I'm also throwing in some movies so you can take the occasional break and see how things are done as many times as you like. ;-)
Remember, every time you refresh the quiz page or click on one of these links you'll get a new quiz to practice with! Here we go ......
- Order of Operations
- Multiplying Decimals by Whole Numbers
- Multiplying Decimals
- Dividing Decimals by Whole Numbers
- Divisibility Patterns
- Prime Factorization
- Greatest Common Factor
- Simplifying Fractions and Ratios
- Mixed Numbers and Improper Fractions
- Least Common Multiple
- Comparing and Ordering Fractions
- Writing Decimals as Fractions
- Writing Fractions as Decimals
- Comparing and Ordering Integers
- Adding Integers
- Subtracting Integers
- Multiplying Integers
- Dividing Integers
So that's a lot of review and little bit on integers. I'm not sure if you started multiplying and dividing integers in class yet. If not, I've got a couple of movies below that help explain how it works. You can get a head start on the rest of your class!!
In future posts I'll continue to include review material from stuff we've already covered to help you improve and stay sharp. ;-)
Now, let's see what's on in the math theatre today .....
There's a lot here ... hmm .... maybe too much ... maybe I went a little overboard!?! ;-) Take it at whatever pace is good for you. Most of it is review. Spend most of your time on stuff that you most need to practice. A ... B ... C ya! ;-)

Adding and Subtracting Integers
First I've got three "leesons" I want you to read. Then you'll practice your skills using the online quizzes below.
Integers (les nombres entiers) is a VERY important topic. You're going to use them in every math class from now on. The good news is, you probably already know a lot about them. Living in Winnipeg you know the difference between positive and negative temperatures. If it's -5 degrees celcius outside, how much does the temperature have to go up to get to +5 degrees? If you know the answer to that question (I put it at the end of this blog post) then you know two really important math facts:
(1) -5 and +5 are two completely different numbers and
(2) when you figured out the answer YOU WERE DOING ALGEBRA! (See, I told you you're smart. You can do algebra without even realizing it!)
OK, here are the lessons:
The quizzes have 5 questions each. If you refresh the page you'll get a new set of 5 questions, so you can do as many as you like. Also, there is a [Hint] button you can click, if you need it, for each question. Here they are:
Let me know how you do with these quizzes. Are they too hard, too easy, too much? (The answer to the question at the top of this post is +10 (positive 10), "positive" because it went up.)
