I love classification work! It is so much fun, I think because language and etymology really come into play and it can be one way of engaging students with some lively discussion.
This set of mammal cards serve as an introduction to the main orders within the class mammalia. There is a picture card and information/description card for the orders covered (18). They have been colour coded as these are the first in a series of resources, as I hope to cover each of the classes.
