The Book Of Perfectly Perilous Math

Here are 24 do-or-die problems from a world where fantasy meets math and survival depends on finding a correct result. How many months would it take a single vampire to completely take over a town of 500,000 people? How long can a barrel of fresh water last before five shipwrecked sailors go mad from thirst? As fun to read to read as they are challenging to solve, these problems draw upon concepts that you're learning in school—fractions, algebra, geometry, expressions and equations, pattern recognition, and more—and make math fun. Then, learn by doing with the 24 hands-on activities that bring the math to life. Sharpen your pencils—it's perilous out there!
