6th grade Math Olympiad students recently created their own Math Clock. Students used exponents, variables, square roots, cube roots, absolute value, math vocabulary, fractions, and integers to represent all twelve numbers on the clock. This clock will definitely be hanging up in my mathematics classroom. Here are some pictures of the clock with the students who designed it.
