This medium worksheet moves from tracing into nine fill in the blank sentences that ask first graders to name groups for a goldfish, an ant, a parrot, a whale, and a butterfly, plus key features like fur or hair, dry scales, and eggs laid by birds. The sheet finishes with a four pair matching activity that links a bear to mammal, an eagle to bird, a salmon to fish, and a beetle to insect. The mix of recall and matching gives children practice both naming groups and sorting real animals into them.
