This is an easier way then sending out newsletters that rarely make it into the hands of parents.
CNN is a great website for current events of all types, a good way to finish off the class period to educate students in things going on around the world.
While it may seem common sense, looking at Wikipedia's "Today in History" section on the front page everyday is a way to engage students into history and make them reflect on the events that happened that day years ago.
