i had a bunch of animal cards that we use for sorting, classifying, etc. i decided to sacrifice a few of them to make realistic zoo cages.
we had a discussion of zoo rules that we know about or that we think should exist. we talked about why animals are in cages which led to a broader discussion of respecting animals. then we went outside and chose some animals to put in cages.
this is simply taking an animal card, cutting off the name, gluing on the animal card, gluing bars over it, adding the animal name. insta-zoo!
