I'm from near B'ham UK originally but I teach kids with learning, emotional and behaviour difficulties near to Zurich in Switzerland.
We have had Moodle for 2 years now and one of my main obstacles was that our kids often have such low reading ages and short attention spans. That made all the wonderful communicating facilities of Moodle a little difficult at first.
We started out using simple Hot Potatoes tests and quizzes (http://hotpot.uvic.ca/) which can be uploaded into Moodle. I also have a few spelling activities of my own (demo at www.manxman.ch/moodle ) which can be used in conjunction with the hot potatoes and Moodle.
Let us know how you get on.
I forgot to mention another bonus of the hot-potatoes suite of software. It is so user friendly and understandable, that the pupils can use it to make their own quizzes and tests.
Gather a few animated GIF files, mp3s or even .swf flash animations, where they can browse through them and embed them in their own hot-pot teaching materials. The response when they see their own work loaded up into the school system is very positive. They also tend to put a lot more "credability" on to the offerings of peers in comparison to teachers' materials.
If they produce a test in their own PC directory, you can simply zip the finished hotpot file and associated graphics into an archive using winzip or similar. You can upload into Moodle and "unzip" in-situ on the server.
I think this aspect is really one of the fundamental principles behind Moodle anyhow. If you want any example files, please let me know.
