WAYSIDE SCHOOL BENEATH THE CLOUD OF DOOM

Rejoice! 25 years later, Wayside School is still in session, and the children in Mrs. Jewls’ 30th-floor classroom haven’t changed a bit.

The surreal yet oddly educational nature of their misadventures hasn’t either. There are out-and-out rib ticklers, such as a spelling lesson featuring made-up words and a determined class effort to collect 1 million nail clippings. Additionally, mean queen Kathy steps through a mirror that turns her weirdly nice and she discovers that she likes it, a four-way friendship survives a dumpster dive after lost homework, and Mrs. Jewls makes sure that a long-threatened “Ultimate Test” allows every student to show off a special talent. Episodic though the 30 new chapters are, there are continuing elements that bind them—even to previous outings, such as the note to an elusive teacher Calvin has been carrying since Sideways Stories From Wayside School (1978) and finally delivers. Add to that plenty of deadpan dialogue (“Arithmetic makes my brain numb,” complains Dameon. “That’s why they’re called ‘numb-ers,’ ” explains D.J.) and a wild storm from the titular cloud that shuffles the school’s contents “like a deck of cards,” and Sachar once again dishes up a confection as scrambled and delicious as lunch lady Miss Mush’s improvised “Rainbow Stew.” Diversity is primarily conveyed in the illustrations.

Ordinary kids in an extraordinary setting: still a recipe for bright achievements and belly laughs.
