Unit 2 Day 4 FOCS – Human Computer Interaction

Journal Entry: Unit #2 Entry #4 Using the numbers 3, 5, 8, and 9 and any mathematical operation you wish, how many ways can you make the number 24? Example:

There are 20 people in a room… Including you… If you shake everyone’s hand in the room, how many hands are you going to shake? There are N people in a room including you. If you shake everyone in the room’s hand, how many hands are you going to shake?

Handshake activity (15 minutes) In your groups determine the following: If there are 20 people in a room and everyone needs to shake everyone else’s hand, how many handshakes are going to occur? If there are N people in a room and everyone needs to shake everyone else’s hand, how many handshakes are going to occur? Three groups will be selected at random to present their solutions...In your explanations be sure to include EACH step of the problem solving process. Be sure you can EXPLAIN your reasoning. If your group is selected and you do not present, you will receive a grade of 0 on this presentation…
