I hope you can see that although being able to display a years' worth of worksheets and slideshows (which is a very powerful feature of Moodle) is useful, it can often be simpler and friendlier to create the task directly in Moodle. If you've already prepared a worksheet, for example in MS Word, you can also copy and paste it (although it doesn't always display exactly the same as your original).
If you are lucky enough to have a projector, a whiteboard, and an Internet connection in your room, why not present your instructions to your class on a web page in Moodle, instead of writing them by hand? You can then plan the course in advance and show it through your projector when you are ready.
If you have a homework task that does not involve the class having to download and take print outs of your worksheet, why not make that a web page?
If you can get your class into a computer room, why not have them view your web page on their own computers and follow...
