Brief Description of Activity
In groups, you embark on a mission to capture “aliens” visiting the earth. Armed with codes left behind by the aliens in their previous trip, you will mark the locations on a GoogleMap that turn out to be straight line paths. They discover a relationship between the codes and are able to describe the paths mathematically using equations.
Through this mission...
You will understand that there exists a relationship between points found on lines (that can be described by equations)
You will need to know that...
- Linear paths can be described with an equation, y = mx + c when placed on a Cartesian plane
- Steepness of a slope can be described by the gradient (m)
Let's trace their footsteps!
On the mission card, you see a set of ‘secret codes’. These codes come in pairs of numbers. Discuss how you would interpret these codes?
- You will be using GoogleMap to accomplish this part of the mission.
- The student assistant to your group would log in to the GoogleMap.
- On the GoogleMap, mark the locations using the symbol assigned.

We are going to transfer the "locations" into a collaborative graphing platform called "TI Navigator".
- Identify the line (and equation) that your points lie on before you SUBMIT your points to the teacher.
- Are you able to tell if...
- any other alien(s) take the same route as your alien?
- your alien is going to meet any other alien(s)?
- there are alien(s) that your alien will never meet?
Look at the paths taken by other aliens.
Give a general description on the paths taken by this team of aliens that are coming to the earth. (e.g. How do you tell if some of them travel together or would meet up along the way?)
Let's read the reports.
