The Very Hungry Caterpillar shows children these steps. Reenacting the story, to music, is a fun way to expand on the book. Pillowcases, one for each child, can be used for the child to pretend to be in a cocoon. If this isn't possible, a large flat sheet can be used. Fold the sheet in half and sew two of the sides so that there is only one opening.
Several children can snuggle in the cocoon together.
Two pon-poms for each child can be used by the children to wave rhythmically as they come out of the cocoon and change into the beautiful butterfly. To make the pon-poms, cut colorful streamers into about one foot lengths. Gather several together and tape one end. The tape makes it easier for the children to hold them. Read the story to the children commenting on how the caterpillar starts out as an egg and then becomes a caterpillar.
