Question

I can prepare lots of materials in advance, and I don't have to make lots of photocopies.

It gives me a chance to listen to all the learners individually.

Whenever I travel abroad, I collect all kind of things to use in class.

I use them as visual prompts for vocabulary with the whole class, then give them out to pairs so they can practise.

I always use one part of it as a kind of notebook for new words.

This 'aid' gives learners the most realistic and interactive kind of listening practice in real time.

This helps with tests, grammar and vocabulary exercises, dictionary work as well as research.
