"Search and Rescue, Part II" Teacher SupportSearch and Rescue, Part II Archived PoW  Student Version Search and Rescue, Part II is no longer the current ESCOT Problem of the Week. The student version allows teachers to use the problem with their students without giving the students access to the archived answers. Teachers can use the link to the archived problem to get ideas of student thinking. Search and Rescue, Part II is a continuation of Part I, which asked students to explore concepts of degrees and angles based on a helicopter flight school theme. In Part II students are applying what they learned in Part I to another situation. This ESCOT PoW could be used as an exploration of angles, degrees, distance, and headings. If you have something to share with us as you use any of the links or suggestions on this page (something you tried and changed or a new idea), we would love to hear from you. Please email us. Alignment to the NCTM Standards  Grades 68
 understand numbers, ways of representing numbers, relationships among numbers, and number systems Geometry  use visualization, spatial reasoning, and geometric modeling to solve problems Measurement  apply appropriate techniques, tools, and formulas to determine measurements Problem Solving  solve problems that arise in mathematics and in other contexts Communication  communicate mathematical thinking coherently and clearly to peers, teachers, and others  use the language of mathematics to express mathematical ideas precisely Connections  recognize and apply mathematics in contexts outside of mathematics.
 This ESCOT PoW is related to a very interesting set of mathematics questions on finding optimal boundary lines. Here is one simple example:
Provide students with this question: There are three schools in a town, indicated in the diagram by x, y, and z. You want to draw up town boundaries so that each student is closest to his or her own school. How would you draw the boundaries?
Hints:
 Logo activities: since Logo is a computer programming language based on a "turtle" turning right or left and traveling forward or backward, there are a lot of good Logo activities involving heading and distance.
