There is also a Fact or Myth question when you are on the main page with a different question each time you visit the page. It explains why it is a fact or myth. You can also choose a date to visit to see important things from that day. It suggests using your birthday, but this could also be fun to do each day to see what happened that day. You could also do the Fact or Myth question and use both as an opener to the day or something for those last few minutes after you pack up at the end of the day. The Super Sleuth game is fun but short. Famous photos of historical people have had something added to them that doesn't fit the time period and students have to find it.
