"Geocaching" (pronounced "geo cashing") is the sport of using GPS systems to locate hidden boxes at different geographical locations across the country. Directions and clues are left in the boxes to aid in the journey.

In the spirit of geocaching, we have created activities called "MathCaching" which use the internet to find hidden boxes to reveal clues to the continuation of the games. Your success at "MathCaching" is dependent upon your skills at solving mathematical problems.

The MathCaching games are subject area dependent. There are free versions of MathCaching for Basic Math Skills ("BasicCaching"), Algebra ("AlgeCaching"), Geometry ("GeoCaching"), Algebra2 (Alge2Caching), Trig ("TrigCaching"), PreCalculus ("PreCalcuCaching"), Calculus ("CalcuCaching") and TI-84+ Caching.

The MathCaching screens are deliberately "large" in print so that they can be projected for classroom use. A teacher answer key (including the URL addresses of all of the boxes) for each free game is available upon request for teachers from a school district email address.

Note to Educators: The free MathCaching games at MathBits cover topics that occur throughout each of the respective courses and are best used for review at the end of the year, or for warm-up at the beginning of the year for the following course.

Each of the MathBits' paid subscription areas (,,, includes MathCaching games for each "topic" area, referred to as the "MathCaching Topic Series" which are played in the same fashion.

The CERTIFICATE found at the end of each Caching Game will carry a date and time stamp WHEN PRINTED.

If your browser is FireFox, be sure to follow the directions below:

Use the Certificate, along with the work shown on the student worksheet, as evidence of a student's completion of the game.

To Play the Open (Free) Versions of MathCaching:

1. Download the MathCaching game's matching worksheet to record your work and your answers.

2. Go to the "START the GAME" internet URL address for your chosen area.

3. Solve the math problem(s) at that location.

4. Follow the directions (based upon your answers) to find the address of the next hidden internet box.

5. Into your browser, TYPE the address of the next hidden box, using your answer to fill in the missing portion of the URL address.

6. When you find the final hidden box, a certificate is available stating that all of the hidden boxes have been discovered. Students may want to print the certificate to share their success with their math teacher, or teachers may request the certificate (along with the completed worksheet) to verify that the activity was completed.

7. Good luck with your MathCaching journey!!

Please note that URL addresses are case sensitive!!
