you could do a scavenger hunt with christmas objects or chocolate. If you have some bells, you could teach the children Jingle Bells. If they dont learn the words, have them identify the words Jinle bells and shake the bells. Blind children are usually very fond of music. If you are allowed to play music, I would. You could adapt musical chairs for your class. You could also play musical statues with christmas music. If you need to know anything else, let me know. I ll try and come up with some more ideas for you. I m a blind teacher, so feel free to ask me for help if you need it. I can tell you from experience, what works and what might be difficult.
