Writing your instructions on the board instead of trying to speak aloud so they can hear you? Using images that illustrate your instructions?

You have to be very creative since your class is small (10 students only. I have a class with 56 10-11 years old students!) and school authorities are not usually keen on helping teachers in your case. They tend to believe you are in a privileged situation working with such small classes. It happens all the time.
