This is a cute book that helps kids with their counting skills. It details what the caterpillar eats as it grows, ie. one apple, two pears. What I always liked about it was the fact that the pages got progressively longer as the number of items the caterpillar ate increased. There are also holes in the paper to signify his bites.
It is a fairly short story with simple words, so younger kids are able to read it with only a little help. Soon they can read it on their own, since it is one they will look at over and over and memorize.
The best part is at the end of the story when the caterpillar forms a cocoon and emerges as a beautiful butterfly. The pictures are even better than the story, with gorgeous watercolor art.
All young kids will love this classic book. I really enjoyed reading it to them when I worked for a tutoring program. I liked how engaged they were because the book is so tactile, and it was also great to see how proud they were that they could read it mostly by themselves.
