The best way to begin British Literature is with the Anglo Saxon time period, and "The Seafarer" is one of the most popular poems from this time period.
This PDF file contains the poem with boxes for students to annotate the poem as they read. Each box is labeled with a letter, and the three reading questions at the end are numbered. The poem with the annotation questions, reading questions, and a constructed response question is 5 pages in length. The answer key is included.
This is perfect for sub plans if you have to miss a day and still want students to complete quality work, or it is great to use with a whole group because it already has the discussion questions built in.
If you use Google classroom, this can be put on your private class page as long as you use a PDF converter like the free IceCreamApps PDF converter (http://icecreamapps.com/PDF-Converter/) to remove the answer key. You could make a corresponding assignment in Google forms so students could submit their annotations electronically.
However, if you prefer the pen and paper approach (or if your technology crashes), this can easily be printed with two pages per sheet (4 pages total if printing front and back) and distributed to students.
