This book follows the ravenous caterpillar's path as he eats his way through one apple (and the pages of the book itself) on Monday, two pears on Tuesday, three plums on Wednesday, and so on, through cherry pie and sausage, until he is really fat and has a stomachache. Discover what happens in the end.

It is good for teaching nutrition, counting, science (stages of a butterfly) and the days of the week.
