 What I'm going to do is I'm going to walk you through a game of wall press. I came up with this idea of wall press as a type of means to dissect a primary document. Promethean boards have changed our world in so many ways. Before I used to just give them a sheet of paper and they looked at it with a partner. I still do that. I want them to see their personal copy because sometimes the Promethean board doesn't give the definition or the specifics that you can see from a distance. So they have their personal copy and they have the Promethean board copy. Half the class is up pressing against the walls. The other half of the class is sitting in the middle. And I put all these questions around the room in all different colors just because I think your eyes crave colors. So it just sucks them in and they grab one of the questions of who, what, when, where, why and how. They look at the Promethean board and they end up forming a question that's based on what word they're pressing against. How did John Wilkes Booth get so close? Awesome question. How did John Wilkes Booth get so close to the president? Then they're going to reflect that question back upon the audience in the middle. The person that created the question can call on three people that are sitting in the middle and they'll try to answer the who, the what, the when, the where, the why, the how. And the best means that they can using the logic from the picture. Because they're so entertained with the show going on, they snuck up quiet. Very interesting. He is so, the people are so engaged in the show that's being presented that he sneaks up without being noticed. Second person, Jonathan. To that place in the stage, there's a door behind it and it's really close. There had to be a back door pretty close that he could slip in through. Well, I'm guessing that back then I didn't have the best security so he probably could get up there. Very interesting observation. Apparently there wasn't great security there. So Megan's pointing out because of lack of security you can slip through. Make sure I come back to that point when we summarize. That's a great, great difference. After the last, the third guess.
