Is anyone else obsessed with whiteboards? I

**love**them. I have a classroom set of 15 so that every pair of students has one. Well, I wanted to do a twist on our Graph Wars activity for my lesson on matrix translations, so I came up with this. I call it**Going in Blind**because only 1 person out of the pair actually sees what's going on!

__The Set Up__**Students are in pairs. One person in the pair faces the “front” or the screen where you display a certain problem and the other faces the back of the room. The two people are face to face. The person facing the back of the room has the whiteboard. On the screen you display a question the partners must accomplish together. The person looking at the screen can not offer up any information unless they are asked a direct question about it. The person holding the whiteboard should ask questions to figure out what the problem is and to get the necessary information of how to answer it. All their work should be done on the whiteboard. However, they c**

**an’t ask “what’s the answer?” or “what should I do?”**

Here's an example picture of what I put up on the screen with the question:

**Write the matrix equation for the translation**.

**The student asking questions should start off asking, "What's the question?" Then they are able to figure out there is an image, so they can ask "How many points is it?" or "What are the coordinates of the preimage?" They keep asking questions until they think they have it right, and usually the question answer-er will help them figure out what they did wrong if they happened to go astray. At the end of each question you switch spots so the other person has a chance to ask questions.**
