Friday Journals--kids write a note on Friday to their parents telling what they learned that week. The parents write a short response back to their child, and the child brings the notebook back Monday. Each parent response earns a sticker for the cover. Love it--a great way to practice letter writing, and to get parents involved. Helps the children ingrain what has been taught into their memory too.

Great tips for parents to help kids choose "just right books." Most important perhaps is to let them try what they are dying to read. Nothing kills motivation like denying a kid the books s/he really wants to read (even if they end up needing a little help--that's just a great chance for shared reading).
