The second part of the activity (not shown) asks them complete three statements:

  1. If the degree of the numerator is greater than the degree of the denominator, then…
  2. If the degree of the numerator is equal to the degree of the denominator, then…
  3. If the degree of the numerator is less than the degree of the denominator, then …

I thought it worked rather well to help them understand why the three different cases occur. We were able to have great conversations about rates of growth. “Weird stuff happens in the middle, but in the long run, the bottom gets bigger faster, so the function goes to zero.”.  I like this approach much better than presenting the “rules” for the three cases and just asking them to use them.

The students conjectures were not a precisely worded as I would have liked. I think that when I use this next year, I’ll still include the conjectures in Part II. However I’m thinking of changing/adding another part that we’ll complete as a whole class where we formalize the wording together.

Any suggestions for improvement would be greatly appreciated!
