The world would be a better place without math or messy roommates. At least, that’s what Ella Hunter believes. Life is about keeping order and avoiding long division, fractions, or really anything with an equal sign.

As the end of the school year approaches, the fifth-grade teachers at Victor Waldo Elementary conclude there’s not enough time to complete a new math unit before summer break. Great news for math-phobic Ella, right?

Wrong! The teachers decide instead to have their students host the first-ever Math Fair. And the fair project is worth two major math grades.

Add in one dead possum plus two horrible roommates who come to stay while their house is being renovated, and you have an equation for disaster. Ella is headed for summer school and math tutoring for sure. Can she stop her troubles from multiplying before it’s too late?
