No, I am not an Arab. And it is not about the witches of Macbeth or any other. I'm simply fascinated with 1001 nights' tales. Students just read the story but ... the 'but' is they need to say some words as they see the pictures rather than read. The moment they get to the gap you click and the picture appears. (Be careful: The 'king' is quite tall, so there seem to be gaps where there is no word missing in fact. )
Hope this should make the students think in English.
Some troublesome vocab I explained in Polish, but you may easily rub this out. Wonder how you liked it.
