Clay, we have the same type 6.5hr Pre K program in FL and my DD is enrolled for fall. I enrolled her for the social benefits and with the hope that since the Pre K is located at the elementry school she will be attending for Kindergarten that it will help with that transition. I plan to send her with her own books each day as she reads chapter books and I'm pretty sure that they won't be availble on the shelf. We will continue to have the work books, work sheets, games and puzzles she loves at home so that she can still be stimulated in those areas. I do have a worry about "nap" time as DD gave up naps at 18 months and I'm not sure how she will handle this, I hope they will let her lay quitely and read.
