Sketchbooks

I have been very curious about sketchbooks and early learners lately.

Inspired by this post and this book.

I see sketchbooks as a very open-ended activity and also a place for brainstorming, working through problems and exploring.  As I read and re-read posts about sketchbooks, I am curious how they can be integrated into the MiniMasters program.  (Perhaps a springboard lesson for the teachers, once I leave?) Hopefully more on this soon.

How have you used sketchbooks with early learners? Any success stories or nightmares?
