I should have been typing up lesson plans. That's boring.
Instead, I read Sarah's blog post about using vertical number lines. My students this year are worse than ever at integers. Ugh. How does that keep happening? I suppose this group's problem might be from elementary school because they're also having trouble with 8x3 and 12-7. Anyway, rather than complain, let's give them tools to get past the hurdle. Sarah's individual number lines are a good start. She mentioned in her post that she wanted a wall version. I've gotten quite adept at MS Word tables lately, so I made one.
Enjoy. I think I'm going to make mine neon green.
EDIT: In a couple of minutes I made a horizontal version too. If, like me, you ordered a number line only to find out it was discontinued (really?), you might need one of these as well.
EDIT 2: I shouldn't do school stuff late at night. In the first version, I managed to make the vertical number line upside down. It's fixed now. I could really use a proofreader! :)
How do you approach students' misconceptions with integers?
