This is a file that will work on any touch device such as an iPad, HP TouchPad, or Android Tablet. It is a PDF file of the Dolch PrePrimer word list. When assessing children on what words they know, I use these as "digital flashcards" on my tablet. You simply flick through the list to display the word. No app is necessary, just a version of Adobe Reader on your tablet, which most come standard with.
