I just found out about two summer reading programs I thought I would share.
Book Adventure is a free online program where kids can find quzzes on many books they have read and earn points for prizes as they pass the quizzes. My daughter and I did several quizzes together today. Two of her favorite series right now are the Magic Treehouse series by Mary Pope Osborne and the A to Z Mysteries by Ron Roy. There were many available quizzes for both of those series.
Also, Barnes and Noble has a reading program. You simply go to the website and download and print the form to fill out. After reading eight books you bring the completed form in to Barnes and Noble and can recieve a free book from a list of books.
