How Sam Shah introduces rational functions - I want kids to build up rational functions, instead of breaking them down. I want them to see how they are constructed term by term by term. Kids need to understand what the first term is doing -- that for any value other than 3, the fraction will evaluate to be 1 (thus it will not affect the rest of the multiplication), but when is 3, we clearly get something undefined and so on. Packet of questions to introduce this.

Master Teacher Tiffany Dawdy's lesson -  'Ahoy again! What can you see now? Building Rational Functions'  Objective: SWBAT to develop a non-linear model and formally define and apply inverse and direct variation.  Big Idea: Students use “spyglasses” again to build context around rational functions and begin to develop an understanding of how a rational function behaves.
