Hi,, you have to rush using the magical weapon (Hands and eyes) but you need to start it perfectly ,, I suggest you say to your class that I will say now something you didn't hear before,, when you hear me saying that you should do two things at a time,, first, you have to leave everything in your hands and fold them together, then only look at me,, eyes on me,, I will say it now,, pay attension,, listen carefully and do,,, then you say it,,( Hands and eyes) you guide them to be very very quiet,, and looking at you, while folding their hands,,
Hope this will work,,
thanks
