I think it was last year when Betsy Hubbard began her end-of-the-month CHALK-A-BRATIONS on her blog, Teaching Young Writers. It's been lots of fun seeing what and how people chalk. Since I moved, I've been 'chalking' on my IPad with an app titled ChalkDraw. Don't forget to go to Betsy's blog to see all the other links to Chalk-a-bration!
