Talk with your daughter's teacher and with the technology specialist at her school to find some software titles that would help her. The teacher can also recommend some workbooks that would encourage your daughter to continue to work at her reading and writing.
Be sure to take your daughter to visit the public library this summer. Many libraries sponsor summer reading programs and contests that may spark her interest. The librarian can also help you find some high interest books that will get your daughter excited about reading, and you can "write" stories together as you ride in the car and then put them on paper later when you are home.
