Primary Level Game:
This level of the game is intended for our younger and beginning players. Primary Clues must have at least 
(1) one coordinate (latitude or longitude);
(2) at least 1 relevant associated date; and
(3) a hemisphere-related clue.  

If subject matter such as math or history is used to give clues, it should fall within the reasonable knowledge area of the ages 9 - 11. Clues should be fact-based as much as possible. Finally, the Landmark must exist or have existed at one time in history on planet Earth.  Clues should enable players to make progress in the searches.  We want our students to become successfulsearchers, collaborators, and problem-solvers!
