Teaching higher level math concepts to elementary students is in itself a challenge. The goal of this set of lessons is to progressively walk a student with basic math skills (two and three digit multiplication and division) in determining the ratio of Pi (π). In basic mathematics, Pi (π) is used to find area and circumference of a circle. You might not use it yourself every day, but Pi (π) is used in some calculations for such things as building and construction, physics, chemistry, mathematics, communications, music theory, medical procedures, air travel, and space flight. Pi (π) is useful.
Note, if you are here to earn the Elementary Pi (π) Certificate it would pay to review the material and the intro to the quiz before beginning.
