Dinosaur Dichotomous Key Problem: The worksheet tasks students to classify the 5 organisms by their characteristics first via a table of similarities and differences. This then scaffolds them to create text and visual dichotomous keys. I’ve provided you with two versions of the problem (characteristics given or no characteristics) for easy differentiation. Answer Keys: Provided for your convenience! Blank Master: For your own personal use in creating more practice problems, or for students to create their own, or even as an assessment piece. ✂ Teaching Suggestions & Ideas Students should have prior knowledge of reading and drawing dichotomous text and visual keys prior to attempting this task. Print the single-sided problem individually, or print two copies back to back for the extra challenge (make TWO DIFFERENT keys of these 5 organisms!). Great for revision, homework, content work (handed straight to students after introducing the topic) or even assessment!
