What's on Your Radar Screen? Distance-Rate-Time Problems from NASA
Keyword(s):
Imagine that you are an air traffic controller on a busy evening, responsible for directing 100 planes per hour heading to a major metropolitan area. (see fig. 1.) your job is to keep all these planes safely separated and on time to their destinations. To do this, you must quickly and accurately solve a multitude of distancerate- time problems. This air traffic control scenario provides an exciting, challenging, and meaningful context for prealgebra and elementary algebra students to “model and solve contextualized problems using various representations” (nCTm 2000, p. 222) that address diverse learning styles and preferences as well as different levels of mathematics preparedness.
