4 Apr

This activity was used with a gifted summer session.  The students were rising 2nd-4th graders. 

The basic idea was that students moved in small groups through 8 different caches.  At each cache, they solved a puzzle that gave them one single digit number.  Once they had all 8  numbers, they went to a final cache.  This cache had two locks on it, each with 4 digits.  They used the 8 numbers they had discovered at the other caches to open the locks and get the “treasure.”  I used a pirate theme, but I actually think a secret agent theme would work even better.

Materials Needed:

  • Cache Hint Cards
  • One box with space for two locks (my dad made mine, but I’ve seen some toolboxes that would work)
  • Two locks with 4 numbers each on them
  • See the slide show below for pics of the contents of each cache:

 

Students first introduced to the activity of geocaching.  They were also given some things to think about when they were solving the puzzles.  I used this ActivBoard flipchart:

Then in groups of 2 or 3, students moved through the different caches solving problems.  When they were completely done, they had the code to open the locks on the final treasure. 

Things I learned and would do differently next time:

  • It would work better to have a demo lock to show in the beginning to teach students how to unlock and relock combo locks.
  • All the groups for one set of students finished at the same time.  There was a run to the treasure box.  I think next time there will be some rules to this part.
