# Day 36: Constructing Rational Functions

One way I’ve found to be sure students actually understand a process is to turn it around on them. My precalc classes have been graphing rational functions and seem to have the process down. But, I wonder, do they really, REALLY get it? So I do a switcher-roo. I give them a graph and they have to write the equation. Or I give them the special characteristics of the function and they have to build the equation.

We did a pass the pen today where each student using a color pen added a part of the equation and noted why that part was necessary. They all wanted to add to the equation…I guess they get it!! Woot-woot!!
