Kerbey Lane

3 Act Math

Act 1

1. How many Kerbey Lane pancakes would it take to go from Austin to Denver?
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 students need to know the distance between the two cities, so I set up a Google Maps Engine for them to play with.

Here is a quick tutorial on the Maps Engine.

And here’s the actual distance if technology isn’t in the plans.


Two more pieces of information, the pancake size and box details.

Pancake Dimensions

Act 3


5. How much would it cost to buy all of those pancakes?


6. How much would it cost to pancake the distance from your house to your school? (Andrew Stadel)

I really like this idea. The kids could make a Google Maps Engine with their school and house on it. This also provides an interesting situation because students have to find the best route to their house.
