In a pair of innovative books for the youngest, the author/illustrator of, most recently, the charming Where Does the Brown Bear Go? (p. 470/C-78) combines the most basic of texts with elegantly simple illustrations. Using only pungently meaningful short words grouped in rhymed quartets (""Dog Boy Cap Skate/Snow Scarf Leash Gate/Hill Sled Pon Park/Friend Smile Friend Bark""), Weiss evokes a winter's day when a boy and a girl with their dogs--also friends--go skating together, plus a family of four making a summer outing to the beach. Four words march across each double-spread, amplified by the clear, subtly colored, nicely composed and varied illustrations. Truly beguiling, these two should be a hit with toddlers as well as with older preschoolers, in lap or group, and will be useful for beginning readers as well.
