Step 1: Open the PDF version of the lesson plans - the Word document will not format properly in anything other than Microsoft Word
Step 2: Once open, tap the center of the screen, then tap the 'Open In...' text that appears in the bottom right corner, or tap the share button (square with an arrow pointing out of the top)
Step 3: Select the desired app, and you should be good to go!
It's as simple as that. Send an email to firstname.lastname@example.org if you're having any issues.
