This medium worksheet helps kindergartners connect animal groups to the special features that define them. Part A presents nine fill-in-the-blank sentences about penguins with wings that cannot fly, a horse as a mammal, toads and newts as amphibians, spiders with eight legs, a colorful parrot, crocodiles laying eggs on land, and dolphins breathing air. Part B is a matching activity where children pair fish, insects, birds, and mammals with the right features: gills, six legs, feathers and beaks, and fur with milk. Children build the classification thinking that supports later lessons on habitats and life cycles.
