This puzzle was shown to me by a group of 4th and 5th graders when I was working with their class. Out of pure curiosity, I was wondering if I was the only person who ran into problems when trying to solve this puzzle. I'm still not sure I would have ever solved this puzzle without one of them giving me A LOT of help. In order to make this puzzle fit with the coordinates hidden in the puzzle, I have been forced to make a few adjustments to the puzzle. Good luck!

On a side note, I never did figure out the puzzle. The kids basically did it and showed it to me because I gave up. I'm not certain if the one they showed me was easier or not. Each row had 4 letters instead of 3. I thought by using 3 in each, it would make it more practicle. Either way, I must admit. I am not smarter than a 5th grader. Are you?
