One of the books we read as part of our letter B project was We're Going on a Bear Hunt by Michael Rosen. The Totally Tots blog has a link to printable pages (http://www.makinglearningfun.com/themepages/WereGoingonaBearHuntPrintables.htm) which summarize the story, and each page has an activity to make the pages more like the story. For the part when the characters go tromping through tall grass, I cut out a strip of green construction paper, and Crumpet fringed the top. Then he glued it into the book. He painted the river with watercolors, fingerpainted the mud, made snow with a hole puncher, etc. It was a really neat activity which involved a lot of different skills and we both got a kick out of it.
