I have a favorite FHE site, here.
It generates crossword puzzles—free. You make up the clues, like so:
Expected/ Sister Hinckley: It turned out better than I _____
Zoramites/ Holy, holy, holy hypocrites
Mooch/ Cat who showed up on Aunt Nikki’s birthday
You push “go.” POOF!—instant FHE lesson/activity. We’ve done family-specific puzzles, a puzzle that commemorated President Hinckley, Book of Mormon puzzles.
Most recently, we read through the Proclamation on the Family, then searched for puzzle clues in the text. Halfway through, my 9-year-old looked up and said, “This is fun!” Cha-ching!
If you try this, it works best “open-book,” with text containing the answers available for everyone. Sometimes I have to draw in a couple of lines that the printer left off the printed copy.
It’s fun, it’s easy, my family stays engaged with the material long enough to learn a thing or two. Jackpot!
