This medium worksheet explores how animal babies grow and what we call them. Fill-in-the-blank sentences walk second graders through a frog starting as a tadpole, a caterpillar changing into a butterfly inside a chrysalis, baby birds hatching from eggs, and reptiles laying tough-shelled eggs on land. Students also learn that mammals feed their young milk and that baby cows are calves, dogs are puppies, and cats are kittens.
A matching section then pairs bears with cubs, hens with chicks, horses with foals, and sheep with lambs. The lesson gets children ready for third-grade life cycle studies.
