A.J.'s third grade teacher, Mr. Granite, is retiring after a million hundred years. It turns out the new teacher, Mr. Cooper, is even weirder than Mr. Granite! One day he's Rat Man and he teaches about rodents. The next day he's Lava Man and he teaches about volcanoes. But what happens when a real superhero is needed? Find out in this first book from the hilarious My Weirdest School series.<br />These irreverent early chapter books feature cartoon illustrations and characters whose antics will have readers expecting the unexpected. The original My Weird School series has branched out into My Weird School Daze (following the kids from second to third grade) and My Weirder School (which brings the weirdness of the outside world to Ella Mentry).
