How to turn these facts into a family trivia night

You do not need a score sheet or a pile of prizes. Choose ten facts, read each one aloud and let everyone guess whether it is true before revealing the answer. For preschoolers, offer two possible answers; school-age children can explain why they chose theirs.

Want to check a surprising claim? Ask, "How could we find out?" Look for a museum, university, government science agency or reputable reference book. Read the source together, and check that it supports the exact claim rather than just discussing a similar topic.

Keep the mood friendly. A wrong answer is a chance to learn something new, not a reason to feel embarrassed. Let your child choose the next category, and stop while the game is still fun.
