  1. Smart Skies FlyBy MathTM National Aeronautics and Space Administration Six Approaches to Distance-Rate-Time Problems in Air Traffic Control Grades 5-9 Free! Beth A. White Greater San Diego Math Council Conference

  2. Overview

  3. Intro to Air Traffic Control During the busiest travel times, about how many commercial planes are flying in the US? About 5,000 planes!

  4. World’s Largest D-R-T Problem vide

  5. Two Classroom Activity Sets • Real-world applications • Hands-on experiments • Multiple representations Free! Free!

  6. www.smartskies.nasa.gov/flyby

  7. Standards-based & Classroom-tested • Rates • Data collection • Modeling • Measurement • Graphing • Problem solving FlyBy MathTM

  8. Analyze 2-Plane Problems Planes at same altitude D = R • T • Which plane arrives first at the intersection? • How far apart are the planes at that time? FlyBy MathTM

  11. Grade Level Focus 4 5 3 1 2 Same Speed Same Speed Different Speeds Different Speeds Different Speeds Grade 5 Grade 6 Grade 7 Grade 8 Grade 9 FlyBy MathTM

  12. A Look at Problem 2 2 Same Speed Students use the Student Workbook to: • Read the problem • Do the experiment • Do the math FlyBy MathTM

  13. Understand the Problem • Speed of each plane = 1/2 foot per second 16 ft 20 ft • Will the planes meet at the intersection? • If not, how far apart will they be when the first plane arrives? WAL27 NAL63 FlyBy MathTM

  14. The Physical Experiment • Students act as Pilots, Controllers, and NASA Scientists. • Students lay out two jet routes. • Pilots step down the routes. • Students measure and record time and separation distance. FlyBy MathTM

  15. Six Math Methods • Count feet and seconds • Draw and stack blocks • Plot points on two vertical lines • Plot points on a grid • Derive & use the distance-rate-time formula • Graph two linear equations FlyBy MathTM

  20. Derive and Use the Distance-Rate-Time Formula d = r t • d t = r 16 feet tWAL27 = = 32 seconds 0.5 feet/sec. 20 feet tNAL63 = = 40 seconds 0.5 feet/sec. FlyBy MathTM

  21. Graph Two Linear Equations 0 10 20 30 40 50 60 NAL63 WAL27 d = 0.5 t d = 0.5 t + 4 t d t d seconds feet seconds feet 0 4 0 0 10 9 10 5 32 sec d 20 14 30 sec 20 10 20 ft. 30 19 30 15 20 sec 40 24 40 20 15 ft. 10 sec Distance traveled 10 ft. 5 ft. 4-ft headstart 0 ft. t FlyBy MathTM Time traveled - seconds

  22. Let’s Slow One Plane d 20 ft. 15 ft. Distance traveled 10 ft. 5 ft. 4-foot head start 0 ft. t Time traveled - seconds 0 10 20 30 40 50 60 What happens to the planes where the lines intersect? Distance from route start

  23. Graphing Visualization Tool • In each panel, we can change speed & starting position. • A change in one panel changes the other two panels. • Helps students link the math to the real world.

  24. Crash or No Crash? • When the lines cross on the graph, do the planes collide? • We can use the simulator to answer the question.

  25. No Crash! • On the graph, the lines intersect at (30, 15). • At 30 sec, each plane is 15 ft from its jet route start. • Note: the planes are on 2 routes that intersect at 20 ft.

  26. Crash! • On the graph, the lines again intersect at (30, 15). • At 30 sec, each plane is again 15 ft from the jet route start. • Note: the planes are flying on the same route.

  27. Challenge! • For 2 planes on 2 routes, configure the graphto represent a collision. • Hint: Where is the only place on the routes a collision can occur? At the intersection at 20 feet.
