|(Pic from my OLD classroom!)|
This year, I decided to take my decorating a step farther and actually map out Slope Dude's journey on the wall. This will stay up all year as a visual. I think my students will mainly use it as a quick reference for zero slope vs undefined slope.
This is made out of four sheets of letter sized paper. I laminated the sheets for durability. This, of course, made it very hard to photograph. I managed to get Slope Dude to be glare-free in this photo, but the number line posters weren't so lucky.
After hanging it up, I decided I should title my posters, too. Someone on twitter suggested I should print off a Slope Dude to place on my posters. Such a cute idea!
See that bit between "Niiiiiice Negative" and "This is zero fun"? There was a bit of the wall showing between those, so I took a bit of the green that I trimmed off "This is" and "zero fun" and stuck it behind to make it look more complete.
My favorite part, of course, is the vertical "UNDEFINED!" section. I hope this reinforces that a vertical line has an undefined slope.
I've uploaded the files here as editable Publisher files and non-editable PDF files. For the title poster, you'll need to download the font "Wellfleet." For the Slope Dude pieces, you'll need to download the font "ArmWrestler." If you don't want to fuss with fonts, just download the PDF version.
