Follow the steps of the “mathemagician” to examine the fascinating characteristics of numbers. In part 1 of this series, learners examine four numerical curiosities: Uniqueness of Unit (Collatz Conjecture), Loop 4 – A Connection Between Math and Spelling, Unique Unit and Loop 4 Revisited, and 145 Is Going in Circles.
In part 2 of this series, learners follow the steps of the “mathemagician” to examine these numerical curiosities: The 189 Challenge; An Armstrong Number: What’s Special About 153? Is 495 Different or Indifferent? Is 6174 Different or Indifferent? It is always 618, and Beginning and Ending the Same.
In this animated object, learners use an algebraic formula to solve the following problem: An airplane travels a certain distance with the wind in the same amount of time that it takes to travel a shorter distance against the wind. Given a constant wind speed, what is the speed of the plane without a wind?
