This medium worksheet asks kindergartners to think a little harder about how butterflies, frogs, and chickens begin and change. Fill-in-the-blank sentences move through the whole journey: a butterfly lays its eggs on a leaf, a caterpillar wraps itself in a cocoon, a baby frog is called a tadpole, a tadpole grows legs to become a frog, and chicks use a beak to crack the shell.

A matching activity then pairs egg, caterpillar, tadpole, and chick with first stage, butterfly, frog, and chicken, helping young learners see that each baby grows into a very specific adult animal.
