An inviting look at the first day of school in Miss Bindergarten's class. The simple rhyming text tells how the animal children get ready for the big event; as a bonus, the names of the students are listed alphabetically, each first letter corresponding to its animal type (Jessie is a jaguar, Zak is a zebra, etc.): ``Gwen McGunny/packs her bunny./Henry Fetter/fights his sweater.'' The procession is interspersed with the preparations of Miss Bindergarten, aided by her pet cockatoo, in her classroom. Wolff's fine illustrations add texture to a fairly simple concept. The teacher is depicted as an efficient sheepdog; eager and organized, she tapes notes on her furniture reminding her to ``have fun,'' yet forgets to take the price tag off her dress. The use of extinct animals for the more obscure letters only adds to the fun. In this soothing introduction to an anxiety-filled event, Slate (Who Is Coming to Our House?, 1988, etc.) makes the first day a pleasure for everyone involved. (Picture book. 3-6)
