How Geocaching Works

Please note Use of services is subject to the terms and conditions in our disclaimer.

Geocache Description:

The cache is not at the posted coordinates. You must solve the puzzle below to find the geocache. The posted coordinates will take you to a basketball court which is a great place to play basketball, but there is no cache there.


The boys and I have been excited to create our own cache, and this is it. There is such a sense of satisfaction gained from solving a geocache puzzle and a math problem, so this cache combines the two. Both of my boys love math, and as a math teacher this thrills me to infinity and beyond J. I know math can be challenging for students, so I have included the geochecker for the puzzle.


Thanks to the City of Madison (J. Weinstock)for giving permission. Anyone wishing to place a cache in a city of Madison park must contact Rhonda Veroeven who will gain permission from Madison Parks representative. To contact Rhonda please email or through WISearchers at
Geocaching activity is only allowed in general parklands in the City of Madison and Geocaching activity is prohibited at: Forest Hill Cemetery, Olbrich Garden, City of Madison conservation parks, Odana Golf Course, Monona Golf Course, Yahara Golf Course, Glenway Golf Course and areas with identified Indian Mounds.
All geocachers will be respectful of all public parkland. No digging or penetration of ground surface will be permitted. Trees, shrubs and plants will not be disturbed or altered at any time.


            The geocache can be found at the coordinates




To find each coordinate, you must solve the following ten math problems [yes it is a test, and I know you may not like that, but hey, nobody said you had to go find this geocache, right? ;-) ]. Each problem has ten answers. Each answer has a digit 0-9 associated with it.

Example problem: What is the ones digit of pi?

3 use 0

1 use 1

4 → use 2

5 use 3

9 → use 4

2 use 5

6 → use 6

7 → use 7

0 → use 8

8 → use 9


The correct answer is 3, so you would use 0 since that is the matching answer. Please note that the correct answer will usually not match with the digit to place in the puzzle. Are your pencils sharpened? Did you pick up a piece of scratch paper to use? Good luck, you can do it….believe in yourself.

Just like in math class, bring your own writing utensil.


Extra Credit J

I often have students who ask, “When will I ever use this?” For extra credit, include in your log when you have used Algebra in either your job or your life. Writing “I never use math” or any negative comments will be accepted in the log but will not earn you extra credit J.
