Student Outcomes

  • Students know the intuitive reason why every repeating decimal is equal to a fraction.   Students convert a decimal expansion that eventually repeats into a fraction.
  • Students know that the decimal expansions of rational numbers repeat eventually.
  • Students understand that irrational numbers are numbers that are not rational.  Irrational numbers cannot be represented as a fraction and have infinite decimals that never repeat.
