Math Games for Middle School

From addition and subtraction to plane and space geometry, simultaneous linear equations, and probability, this book explains middle school math with problems that kids want to solve: "Seventy-five employees of a company buy a lotto ticket together and win $22.5 million. How much does each employee get?" Intriguing facts about the history of math show what a human creation it is, and human errors are revealed through explorations of both Maya and Hindu concepts of zero as well as Mr. William Shanks' 1858 attempt at hand-calculating pi.
