Smiley Faces Answer Key

Original Document: Dichotomous Key with Smilies

The link above will show you the original document with the dichotomous key so that students can identify the smilies. Remind students to always start with the #1. I find them trying to shortcut by just randomly starting at a number in the middle, I've never understood why they do that. It is also for that reason that I do not number the smile pictures below, as the extra numbers tend to confuse, students will try to match them. Usually, once students get the hang of using this type of key to identify animals, it becomes very easy for them.
