We love word finds. I love making my own word finds and using words that my boys like. My place of choice is the Puzzlemaker at Discovery, but simply type "word find" into your favorite search engine and you'll come up with loads of options.
I recently did a word find of dinosaur names for my younger son. I did one of Doctor Who words, and another one of scientific words for my older son. I've done them with Book of Mormon names or names of our extended family members.
They're fun to have in my purse for car rides or times when we're waiting. They're great for General Conference or Sacrament Meeting. You can make them to go along with the theme of an FHE lesson. When I was a cub scout den leader, I often did word finds or crossword puzzles for my scouts that corresponded to the monthly theme.
