As you sing this song, have the children find the words in the puzzle.  Challenge them to find all of the words before you can finish singing the first verse 4 times.  They can do this individually, in pairs, or with a big one on the board.  I plan on printing mine 34x44 and laminating it.   That way we can use dry-erase markers on it and use it multiple times. 
 
Bear testimony that if we search our scriptures as hard as we searched this puzzle, we will find the truths and treasures within the scriptures. 
 
Happy singing!
