Here's a 20-question short-answer test on Beowulf along with an assignment wherein students identify ten important "weapons" in their own lives.
The test is printable, but a Google Doc link is also provided in case you prefer an online experience. The weapons assignment is great for homework, groupwork, or classwork. Just be sure to explain that you're not talking about hurting others weapons, but more like skills that help yourself. Once they get it, they don't question the assignment. No other assignment I found could make Beowulf more relevant to kids today.
