I wanted to share this post I saw in the QUAT listserv because I was always searching for a way to complete worksheets when my daughter was in school. Technology is a wonderful thing! This was posted by Matt Kennedy on the University of Kentucky's listserv (QUAT):

I make sure there is a folder within the student's OneDrive that is shared between themselves and the teacher and have them save the scanned PDFs into that particular folder. That means that once the student is complete with the assignment they can just exit the PDF annotator and the OneDrive app will take care uploading the file to the cloud and the teacher will have access to the completed assignment within a few seconds.
The OneDrive app has completely eliminated the need for any other app that is used for completing paper-based worksheets digitally, no need for emails going back and forth between the student and the teacher, everything is handled seamlessly through the cloud. Teachers and parents have been ecstatic with the ease at which worksheets can be completed and handed back to the teacher while saving numerous steps as compared with other apps on the iPad that I've used in the past. I don't even think Microsoft has realized the kind of gamechanger tool they have created for struggling learners with the OneDrive app for iOS!"
