Kerbey Lane (Part 2)

3 Act Math

Act 1

1. How many steps is it from Kerbey Lane to campus?
2. Write down a guess.

Act 2

3. What information would be useful to figure this out?
4. Write down some questions you have in your head right now.

The kids need to know how long each step is. This is a great opportunity to get the class out of their seats and measure a bunch of student strides. Find a nice average, and you’re good to go.

If that’s not feasible, here’s the average human step length according to Google.

Average Step Length
In order to find the distance between Kerbey Lane and the college campus, you could use a Google Maps Engine for the kids to explore. They can determine a best path and use the measurement tool to calculate the distance.

Here’s a quick tutorial to give an overview of what the Google Maps Engine is.

But, if technology doesn’t permit, here is a distance you can use.
Possible Route

Act 3

Better Act 3

This is a call to teachers in Austin, Texas. I think it would be awesome if someone did a little class field trip to test the results. After the kids do their calculations, actually have them walk from Kerbey Lane to campus.

If you’re not in Austin, I think it would be neat to have the students walk to a local building or maybe the school track. Just something to get them outside.


5. How many pancakes would be needed to pancake the distance from Kerbey Lane to campus? (Andrew Stadel)
6. How much would all those pancakes cost? (Andrew Stadel)

Something to consider for the sequel:

Pancake Dimensions
