Summer reading is one of my absolute favorite programs to participate in. The kids get to do fun activities and I get to make sure that they are (hopefully) still retaining some of what they learned in the past year.
Some of my favorite online programs are...
Barnes and Noble Reading - Barnes and Noble has a wonderful program where you can earn a free book off their summer reading list when your child brings in a completed reading list that you can download from their site. They also have activities that you can download from an exclusive kit too.
American Girl Read-a-palooza - Besides in-store events all summer long, their website is full of reading resources, American Girl trivia and character spotlights.
Book Adventure - Book Adventure has a "Create your own Reading Challenge" for kids and a lengthy resources list. One of my favorite things on this site is how children can come back after reading a book and quiz what they've read and earn prizes. Win, win!
Scholastic - Read what you want for Scholastic's Summer Reading Challenge. Kids just log their reading minutes each day and set weekly reading goals to earn prizes. The also have the opportunites to take extra challenges as well. All minutes count towards a World Record goal and a "How Far Can You Read?" chart (right now we're at Big Ben.)
These are just a few of the online summer reading programs available but don't forget to check at your local library for their programs as well. Our local library has a fantastic program each year and we have a huge summer-end party at the end. Does your library have a summer program?
