Sometimes when planning a unit, I browse through the Desmos Activity Builder. When searching for Rational Functions, I came across Dylan Kane’s Building Rational Functions Activity. Excellent. I now had a muse. Here is what I came up with for college algebra:
I like to gush over my students when they do awesome stuff, and this was no exception. I love it when my classroom is abuzz with sense-making conversations. I feel like this activity helped students become more comfortable with the structure of rational functions and how that equation structure is reflected in the graphs. Thanks, Dylan, for inspiring some awesome thinking in my class today.
