This is a quick graph matching worksheet I whipped up using Demos. All of the graphs have the same window. I want my students to get good at quickly identifying "parent graphs" so although this will be a "formative assessment" I will still time the quiz and score it but allow my students to do various versions of the worksheet to improve their scores as desired.
If you open the file you will notice I have included two versions of the worksheet. They are subtly different. In class I will make sure that neighbors don't have the same version.
