Snack Pack Books

Little, Brown as a purveyor of breakfast foods? In the case of the publisher's clever Snack Pack, it only looks that way: this shrink-wrapped trio of ``cereal'' boxes actually teaches basic geometric shapes by means of packaged pop-up books-Circles, Triangles, Play Squares. Edmon J. Rodman's simple texts pack considerable ``nutrition'' for growing minds, while Ted and Linda Bick's colorful, heavily outlined pictures might be considered snap, crackle and pop art ($8.95, ages 3-5 ISBN 0-316-15241-2 Apr.).
