Here is a website I found all about big cats with helpful information on how to distinguish between them. www.BigCats.com There are beautiful photos under "Learn to Identify Big Cats".
The term big cat - which is not a biological classification - is used informally to distinguish the larger cat species from smaller ones. One definition of "big cat" includes the four members of the genus Panthera: the tiger, lion, leopard, and jaguar. Members of this genus are the only cats able to roar. (The leopard, while a "big cat" in this context, is actually smaller than some cats outside of the Panthera genus.) A more expansive definition of "big cat" also includes the cheetah, snow leopard, and cougar. These "roaring cats" are also sometimes distinguished from the other big cats by the term great cats.
Despite enormous differences in size, the various species of cat are quite similar in both structure and behavior, with the exception of the cheetah, which is significantly different from any of the big or small cats. All cats are carnivores and efficient predators. Their range includes the Americas, Africa, Asia, and Europe.
Some of these pictures I took and some where taken by someone else. The ones you can enlarge I took.
You can enlarge this picture. As part of the lesson on the parts of the tiger, the teacher would hand write the parts as they were being presented.
Matching cards and parts of the lion. This one can also be enlarged.
This picture cannot be enlarged. The children match the types of furs and can also feel the difference in softness.
The small cats on the orange plate are for transferring. The strips with the small cat on one is to measure how many little cats long are the strips. There is also some other transferring beads activities and the little fur balls are for cards and counters. These would be the counters!
