Things to Learn

  • Understand that a ratio is an ordered pair of numbers which are not both zero.
  • Examine that a ratio is often used instead of describing the first number as a multiple of the second.
  • Use the precise language and notation of ratios (e.g., 3:2, 3 to 2).
  • Discover that the order of the pair of numbers in a ratio matters and that the description of the ratio relationship determines the correct order of the numbers.
  • Conceive of real-world contextual situations to match a given ratio.
