Provide students with a sheet of paper, which they will divide into two columns - one is the Yay column and the other is the Yuck column.
The students then look through the chapter/unit/book. They will sketch pictures of things they're excited about (Yay) and things they're dreading (Yuck) on their paper.
It's a nice way to give the students an overview of the upcoming material as well as get some insight as to how they feel about what's coming.
