This medium worksheet walks first graders through complete butterfly and frog cycles using nine fill-in-the-blanks in Part A. Children write that a butterfly lays tiny eggs on a leaf, that the egg hatches into a caterpillar, that the caterpillar wraps itself in a chrysalis, and that a butterfly emerges. The frog track follows an egg growing into a tadpole that grows legs and loses its tail, plus a chicken starting inside an egg.
Part B is a four-pair matching exercise linking egg, caterpillar, tadpole, and chick to first stage, baby butterfly, baby frog, and baby chicken. Together the parts strengthen sequencing and the idea that babies look very different from adults.
