The book of perfectly perilous math

759916612

by Sean Connolly

Uses perilous situations to inspire readers as they solve word problems using fractions, algebra, geometry, probability, expressions, and equationsA blend of middle school math with fantasy to create an exciting adventure in problem-solving. These word problems are perilous, do-or-die scenarios of blood-sucking vampires (How many months would it take a single vampire to completely take over a town of 500,000 people?), or a rowboat of 5 shipwrecked sailors with a single barrel of freshwater (How much can they drink, and for how long, before they go mad from thirst?). Each problem requires readers to dig deep into the tools they're learning in school to figure out how to survive
