Cut one circle of construction paper, about 5 inches in diameter. Allow the child use the markers or crayons to draw the caterpillar's face.
Cut multiple circles of construction paper in slightly smaller circles, about 4 inches in diameter.
For each book the child reads, print the title and author on one of the colored circles.
Let the child decorate the circle by drawing a picture from her favorite part of the book. If you want to encourage a slow reader with a fast-growing caterpillar, use a second circle for the picture.
Glue the first book circle to the caterpillar's head, overlapping the two circles by approximately half an inch.
Mount the caterpillar to the wall using poster putty.
Glue each subsequent book circle to the caterpillar in the same way. According to your wall space, your caterpillar may be climbing up the wall vertically, or in a wavy horizontal line. Position the display however you and your child prefer.
