Getting kids to read over the summer can be a constant nag. The lure of screens is strong, after all.

Before school let out Austin Independent School District and BookPeople held a Summer Reading Bash.

If you missed it, Half Price Books has an event this Sunday at 2 p.m. at all of its locations to encourage reading and avoid the summer slide (that phenomenon that happens when kids come back to school in fall having lost some of the skills they left school with in spring).

This year's Feed Your Brain program includes the theme "Out of this World" to celebrate the 50th year of the Apollo 11 moon landing.

At the event kids can pick up a summer reading log (or you can download one at HPB.com/FYB). Once kids have read 300 minutes, they can turn in their reading log and earn 5 Bookworm Bucks to spend on books at the store.

Half Price Books has on the HPB.com/FYB site lists of great books by age group as well.

In the Austin-area, you can find Half Price Books at Anderson Mill, North Lamar Boulevard, Parmer Crossing, South Lamar Boulevard, Southpark Meadows and in Cedar Park, Round Rock and San Marcos.

There are more book reading programs to inspire you.

BookPeople and Austin school district have the 5 Book Summer Reading challenge.  The whole idea is reading five books over the summer can help avoid the summer slide. Pick up a bookmark at BookPeople or download one at 5bookdive.org to record the five books you read. Show your completed bookmark at BookPeople to get a $5 gift certificate to BookPeople. Then turn in the bookmark to your school librarian in the fall to be recognized as a Summer Reader. BookPeople also has recommendations by grade on the 5bookdive.org.
