I skipped enough review stuff in Precalc this year that we're actually going to have a good chunk of time to introduce some limits. I haven't gotten to this point for several years and am looking for ideas.
How do you introduce the idea of a limit? I found Shawn's idea of using rolly chairs and stop watches to find speed and steer them towards the idea of a rate... which leads to slope... which leads to a limit.
I honestly don't know if I could pull that off (especially the rolly chairs thing).
Any other ideas?
