This is a one page (double sided) work sheet that shows students what type of alphabet Vikings used. The "futhark" alphabet it shown with the corresponding english sound below it. There is a riddle to solve, a few Viking words to translate, and then has students answer a few questions about themselves in runes as well. I've used this in World History talking about the Norse people, Mythology, in a unit on Beowulf, and I'm sure it can be used for many other subjects as well.
In case you do not have a background in language, I have two helpful hints for solving the worksheet: W = V, and the letter that looks like a weird P = TH.
