Should've, Would've

So the lesson plan says: "The kids know what they should be doing."

What?

Sure they are in the 9th grade, sure they have brains in their heads, but let me tell you this--the kids have no idea what they "should" be doing.

They probably can't remember what chapter they are in, they have no idea what concepts they are learning, and they don't have a clue what they have due.

Or at least they won't admit it.

If the teacher says that the kids know what they should be doing, I can tell you what they will be doing. They will be playing a lively, two-hour game of Pictionary.
