Students and teachers enjoy trivia. While I may be teaching how to navigate specific sites, they both get side-tracked checking out "what happened on this day in history." It's funny how you can prepare for lessons and predict that they will visit these sites at some point during instruction usually when they are supposed to be doing something else. I try to be one step ahead so I check out the daily trivia before instruction time so I can toss in a fact before they slip away to browse the daily sites. It all helps in the illusion we create of being all knowing. If you'd like to practice your Penn & Teller illusionary tactics of brilliance, check out these sites:
The World Almanac Blog has daily facts on each day in history.
Internet4Classrooms includes a page of your daily dose of the web with web sites which change content on a daily or weekly basis. If you don't regularly check out these resources, you are working too hard and reinventing the wheel. Susan Brooks and Bill Byles have gathered an impressive variety of sites that teachers find very usable. I particularly enjoy the Interesting Trivia when I am not entrenched in coordinating standards with web resources.
Side Note about Penn & Teller: when my boys were 5 and 7 years old took all four to visit Davis Kidd bookstore (an independent bookstore) in Nashville, Tennessee to see Penn & Teller. Unfortunately we were late so the boys missed most of their talk and only arrived in time to buy their book and get it autographed. They brazenly demanded magic and were so determined that Penn & Teller obliged. (If you knew my boys then, you would have done whatever it took to make them go away, too). For years the boys practiced the same tricks they saw that day. One year for Christmas, son #2 requested a magic kit and book. He gleefully opened his book but soon after called out in dismay, "Hey! This isn't magic. These are just tricks." Disillusioning a child is so hard. Let's go back in time to that day in history when illusions and magic reigned.
