|This is the starter map. Load this file onto student iPads as it is the correct aspect ratio. Students will see the map image in Choreo Graph and then create a subway map with this as the background. (Students can also use the subway map that they already designed from Lesson 1.)|
|One unit on the grid in Choreo Graph = ¼ mile = .25 mile|

1-2 class periods
These lessons are designed for students to work individually, in pairs, or in groups. Each student should do all the work on their own sheets, and the iPad should be shared across group members as equally as possible.
We suggest that groups be no larger than four students. Four or more students in a group will require extra attention to make sure that every group member is contributing equally.
If necessary, have students label their iPads so they will be able to return to them for the next lessons.
1) Using the subways lines that you created on your map, the coordinates from your table in Lesson 1, find the following total distance that a passenger must travel on a train to make the following trips, (show your work using the distance formula):
2) Based on the distances you have calculated, what do you estimate the total distance of subway tracks to be on your entire map? (Show how you arrived at that estimation.)
3) Now that you have found some distances that your citizens will be traveling to get from one point to another, do you notice any aspects your map that could be improved upon? For example, do you see the need for a line that wasn’t there? Or, are there lines that you could leave out?
4) Did you draw a subway line directly from Armstrong to Jones? If not, why not? Wouldn’t that be the most direct route?
5) What is the most difficult or tricky about using the distance formula?
|The map students use for this lesson should look something like this map. Choreo Graph provides the coordinates and line segments representing the subway lines.|
