I love the book Notice and Note by Kylene Beers and Robert Probst. First of all, I read it during Winter Break and even before I got halfway I knew this book was going to change my teaching. There are so many things I love about it -- but I set out to make my signposts cute and quickly!
If you have a projector, these signposts will work great for you! They start with an overview (available free to check out the quality of the rest of it), and then each signpost is along the road with the phrases written out clearly.
I use this with my students when I introduce a new signpost.
