This is a classic activity designed to get students to think critically about the positive and negative points of different people.
The PowerPoint sets the scene. Tell the students to imagine they are on a sinking ship. There is a deserted island nearby. They get on the only lifeboat. There are 13 people still on the ship, but only 6 more can fit on the lifeboat. Who would you save?
A worksheet is provided to go along with the PowerPoint. I used the white board and a marker to write the students' comments about each person. I went through each person one by one and made the students give me at least 2 positive and 2 negative things about each. Afterwards, the students were asked to make their own list. It's pretty self-explanatory when you see the worksheet :)
