The purpose of this activity is to help students become more independent programs and see the surprising link between co-prime numbers and PI, that transcendental number that just keeps popping up everywhere.
- GCD or HCF
- For / EndFor
- If / Then
About the Lesson
In this activity students use the GCD (Greatest Common Divisor or Highest Common Factor), Randint (Random Integer) a LOOP and IF THEN statement to write a simple program. There is less scaffolding in this activity, students are required to write their own program! The proportion of randomly selected integers that are co-prime has a very interesting result, believe it or not, it is related to PI.
