PDFs are a great way to distribute notes and answer keys to my students. PDFs also help because when you create a PDF it retains the form of the original document. This is essential as a math teacher because of the extensive use of MathType problems. Without PDFs those math equations may loose their form. While researching how to edit PDFs I noticed that with a copy of Adobe Acrobatic Pro you can edit PDFs but I had no idea how many other benefits a Pro account had. My classroom computer has a copy of the Pro version and a brief list of things I do with it is below.
1) Print as a PDF: I know that this is already an option from with Chrome (and it is free) but it is nice to open a Word document (or any program with print capabilities) and just choose "Print to PDF" to create a PDF version of my notes.
2) Convert Picture Files to PDF: From my time using Google Drive I have found that the most useful way to put answer keys for student access is as a PDF. I like to take photos of an answer key with my iPhone and then use them but they are a jpeg file. With Pro you can right click a picture file and "Convert to PDF" right from the desktop. Then I put that PDF in my Drive so my students can access it.
3) Combine Multiple Files Into One PDF: There have been many times that I have had several PDF files but wished I could combine them into just one PDF document. With Pro you can select multiple files (PDF, picture files, etc) and combine them into a single PDF. You can also choose specific pages from within them in case you want to leave a page out of the new version.
