For the second half of the chapter: "I can't believe it." I do the work from the textbook, then we did a quiz. I have teams in my class, in each team they have a whiteboard. They look at the picture and have to decide whether it's true or false.
If it's true, they write: I can't believe it.
If it's false, they write: I don't believe it.
They really loved it because it was competitive.
