ipad pro workflow for teaching and file managers

So far so good. Where I am at a loss is

how to find all pdfs files and other ( not picture or sound ) files on my ipad in one place.

ios doesn't have a file manager. It's up to you to organize you work by applications. Suggest you put all your pdf files in one app.

GoodReader

-- With GoodReader on your iPad/iPhone, you can read virtually anything, anywhere: books, movies, maps, pictures.

-- sync with Dropbox, OneDrive, SugarSync and any WebDAV, AFP, SMB, FTP or SFTP server

-- The types of annotations that can be created and edited in GoodReader include typewriter text boxes, popup comments ("sticky notes"), text highlights, freehand drawings, lines, arrows, rectangles, ovals, cloudy shapes, text underlines, strikeouts, text insertion marks.

I do not know if spotlight has been enhanced to look in applications, but you could try a search.

also how to find a wordprocessing tool with an " open" or " save as " option in the file menu.

Are we talking about your laptop. There is a "fix" to get "save as" to reappear. I've made the change. Now I have to remember what web site provided the simplest change.

Apple put in a well hidden option to turn save as… back on.

See here [ maybe ]

one important thing to note you must use the ellipsis, three dot, character … not three periods in a row. You should be able to use from here.

in 10.10.5

There are all-in-one apps that act like file managers.

fileexplorer

These tend to change & I haven't updated them recently.

All of the "Office" document editing applications on the iPad have limitations. Best try them out to see if they meet your needs.
