I see that Live Education does the story of Beowulf in Grade 4, presumably as part of Norse Studies, but I did it as an 8th grade block. I could also see it for ninth grade and a transition into high school. My favorite part: Natalie wet felting Grendel lurking in his dark cave, looking out enviously at the light streaming from Heorot. This piece is lovely... my photos do NOT do it justice!
I've already written a webpage with my notes from teaching this story. Here are the photos of Natalie's main lesson book. I did this as a short 2 week block, so we used the small main lesson book size from Mercurious (link is to Meadowsweet Naturals, my preferred store for MLBs). If I did this again, however, I think it would be a perfect block for making loose pages and then binding them.
