Class Mammalia - Teacher's Guide

Note: Mammal orders and classification change, and some books may have different answers depending on how current the book are. How detailed the answers and descriptions are depends on you.

There are two possible ways to have your students complete the chart - they can do it as an individual or group project where they use their books and other resources to find the answers, or they treat this chart as notes and you can talk about each group, who pictures and discuss as they fill in the table. I use the Mammal Powerpoint Presentation with this chart because there are some fantasic images of animals and short video clips that the students enjoy. This method does take some time though, plan for at least two days and perhaps more because students will ask a lot of questions and share stories about their own animal encounters. Mammals are just a popular topic!
