This easy worksheet helps second graders tell birds and fish apart by sorting a robin, parrot, and owl into the bird group while putting a trout, salmon, and catfish into the fish group. Fill-in-the-blank sentences add useful vocabulary, showing how birds use wings to fly, how fish breathe with gills, and how robins build nests from twigs and grass.

True-or-false questions check that all birds have feathers and that parrots can copy sounds, while clearing up tricky ideas like the silly notion that salmon nest in trees. Children leave knowing the body parts and homes that make each group special.
