Students love a math race through the United States! Groups start at Washington, D.C., and solve math problems all the way to California! If they miss problems, they are given a "flat tire" problem to solve. They are practicing math skills while reviewing geographical knowledge of the states! Skills practiced: add and subtract integers, circumference, decimals, fractions, percent, measurement, polygons, whole number operations, etc I teach 5th grade and I made a race for my fifth graders foun
