The authors, junior high students and best friends David and Asa, along with best-selling author Marya Washington Tyler, took the kind of gooey, slimy, disgusting science facts that students love and turned them into hilarious math problems. Your students will enjoy trying to determine what percent of the refrigerators in the U.S. contain moldy food. When's the last time you had your students figure the weight of cow manure produced in the U.S.? How many 8-ounce coffee mugs will an average person's sweat fill? What is the number of saliva droplets expelled in one class period? Your students won't mind math when they get to figure the cost of a meal at the Aftermath Restaurant, with foods like Deep Fried Lint, Pseudo-Chicken Parts, Wax Fruit Bowl, and Hot Sludge Sundae. Even the answer key is hilarious. These and other intriguing problems await your students in this book designed to teach children to translate statements and questions into mathematical equations. All the problems are based on known scientific facts. For even more exciting and strange math problems, see the original It's Alive! Grades 4-8
