You can do tons of things to make it fun. Charades, crosswords, word search, mazes, ... apply any fun thing to it. Pick words and discuss the word.. as in idols... list different things folks use as idols. Just let your imagination go.
For fun I put in the search in yahoo... bible study activities and came up w/ 4,470,000 sites. A lot will be children's but I saw couples, teen, women, etc. Go check it out. 🙂

RW,

Isaiah may appear to be a hard book to read, but it really boils down to this theme: Israel has not been keeping the Lord's commandments, and the Lord pleads with them to start doing so and tells them of consequences if they don't repent.

I suggest getting a book about Isaiah, or perhaps articles from the Internet, to get a better idea of what Isaiah is about. Perhaps reading what others have written about Isaiah could help you understand it better. Reading such things always helps me.

The best to you!
