Fun activity #3 is Jeopardy (¡Arriésgate!) courtesy of the great web 2.0 tool Jeopardy Labs (free and no account required!).

I've known about this tool for a long time but never just sat down and used it. It's easy to make and easy to use (except there's not really a function for no one to get the answer right--it keeps the question on the board until you give someone points for it).
I recommend that you stay away from categories like "conjugations" and "fill in the definite article." You can easily make it fun and more communicative by looking at your vocabulary and asking yourself, "What actual questions can I ask with these?" So you could have 'ropa' (clothing) 'comida' (food) 'opuestos' (opposites) 'en la casa' (at home) and then make all your "answers" target-language clues. So for 'closet' put 'where you put your clothes in your room' - avoid students getting confused by making all the "questions" start with the same letter.
Try mine (in Spanish, of course). My students are advanced so you can see some of it would be way over level 1.
And remember - answer in the form of a question. :)
