I use this worksheet as a graded exit ticket once my students have learned a basic overview of taxonomy. The worksheet covers topics such as Aristotle, Linnaeus, binomial nomenclature, and the seven levels of classification. In addition, I have included a bonus entry ticket that I give my students the day prior to this graded assignment. I find they both make a great check for understanding prior to a formal test. Both worksheets are in Word for easy editing and answer keys are included. Thanks!
