Frog and Toad Are Friends (by Arnold Lobel)

The adventures of these two amphibians make for some of the simplest -- and most enjoyable -- chapter books for developing readers. Toad and Frog are, indeed, friends, and their respect for each other comes through on every page. Arnold Lobel's writing is engaging without being cloying, and the vocabulary is basic without being babyish. The story is illustrated with swamp-toned sketches of the friends and their surroundings.

Even though the characters are fictional, the feelings they share (and convey to their young readers) are very real, and the care they show for one another and the world around them stands as a good example of behavior. Children seem to relate strongly to these tales. In response to "The Letter," in which Frog becomes Toad's pen pal to fulfill his friend's desire for mail, one boy said, "I never get mail either! That is sad!" The themes of friendship and growing up seem to resonate strongly--even if they're expressed by amphibians.
