Oh .. you have been so kind to spend some time in my thread .. thanks alot for the idea ..but don't you think it's difficult for beginners of English to role play these roles without having an idea about the three forms?? ( By the way, I teach in Palestine I'm an Arab and so my students are )
So, I think you still not having my point . I mean by real situation for example when i want to teach the present contionous I let about 10 students to come out and give them diffefrent things to do e.g playing football, skipping, drwaing a flower , writing a name ....etc. then I ask what X is doing? She's playing football , she's ......... etc.

So, in that way ss. will deduce that present con. is an action happing right now and continues until the time of our speech .. so, I need a similar situation that I can gather the three tenses past simple, present perfect, and present perfect con.
I thought of having a girl infont of class : I will ask ss what's the time and write it on the B then I'm going to tell the girl " Draw 20 flower on the board " then while she is drwaing I will ask when did she start? she STRATED 2 minutes ago, How many flowers has she drawn? How long has she been drawing?..etc..

So, what do you think ? do you ahve any other similar situations??the problem is that I can't use how far I used how many instead of it with the presnt perfect so do you ahve any situation that can be used with When did? how far? how long?
thanks alot for being interested in my subject!
