This activity is a great way to review Order of Operations in increasing difficulty while fostering teamwork and error analysis. My students LOVE relay races! This particular relay race has students practice Order of Operations (no variables) using addition, subtraction, multiplication, division, exponents, fractions, square root, and absolute value. I used it as a first week warm up for my 11th grade Advanced Algebra class, but it could easily be used for younger grades as well.
