Gr. 2-4. Homework makes no sense to Hari. Consequently, he eagerly trades one of his five senses to a gnome for doing his lessons. That arrangement works well--until he unwittingly trades away his common sense. The jungle gym, the teeter-totter, and other equipment turn tables on the playground bully; and a mealworm named Bob helps a little girl spell accurately. These are only a few of the wacky takeoffs on third-grade experiences that will have readers laughing out loud. Cleverly disguising lessons on good school behavior in plays on words, fantasy, and humor, these imaginative stories delightfully re-create recognizable school situations and characters.
