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.)
