Watch Sal Khan talk about sets of numbers.
Compare what he talks about to what we do/did in class about sets of numbers. I hope that his lesson will help clarify the sets of numbers discussion from class. Know that you can always use his lectures/site for helping you learn the material from class. I know some of you already do. If you don't know of this resource on line, then this blog is all about having you learn about Khan Academy.
In your blog, please write about how YOU will learn to keep these sets of numbers straight. Find a mnemonic device that will help you remember, for example, the difference between the integers and rational numbers. Go ahead, google to see if there's something that someone else has already come up with that you think will be helpful. Or come up with your own idea.
Before you start on this blog, be sure that you make yourself familiar with the blog grading rubric.
Also, I'm thinking that we'll do a better job with blogs this semester; we'll have a blog due every day 9. I'd like your responses, positive and negative, to this.
