Superhero School - Aaron Reynolds - Bog

It's Math Curse meets The Incredibles!
Leonard is no ordinary kid-he's enrolled in Superhero School, where leaping tall buildings in a single bound is child's play. If only long division, fractions, and multiplication came as naturally! But when Mr. Tornado and the rest of the teachers get kidnapped by some ice zombies, Leonard and pals will need to use their math skills if they stand any chance of dividing (and conquering) the enemy.
