If you are brave, you can use physical games. One that I’ve used is where each person introduces themselves by standing up, saying their name, and adding a movement to express their name. They might do this a couple times, and then everyone stands up and says that person’s name and does their movement. You go around the room and everyone gets a chance. This can also be done with music, although I don’t think it’s appropriate in your case.
What this does is it gives everyone a chance to introduce themselves, express themselves, and add a physical image of themselves. In copying, the others get a chance to feel the name, but even more importantly, it aids in remembering the name. Since this is a school, and some learners are physical learners, some aural, and some visual: this works for all. It also teaches professionals that they can design classroom experiences that include something for everyone.
