What's a plus? What's a comment?

Lately, we've been talking about how good writers add things like pluses and comments to their writing.  There's a difference between the two and my hope is that by now, students can articulate those.  

A comment can be something as simple as "I think that's really exciting" or "I'd like to try that someday", but a plus is a bit more.  A plus has a bit more muscle than a comment. 

These are the slides from our Morning Message where the concept of a plus was introduced last week.
