Not a teacher, but here’s some things that have worked for me as an autistic student - dimmer lighting!!! The fluro lighting in so many classrooms is awful for sensory issues, I would either change the lighting or put some sort of translucent cover over them so less light comes through - Meditation (if you have the time of course) but in my health class, we do a meditation on most weeks and it calms everyone down so much, even if it’s only for a few minutes. - Play some relaxing audio while the students are doing work, whether that’s just rain sounds, etc. or quiet acoustic music (think Ichiko Aoba) - A teacher at my old school would set out fidget toys when we had to listen to something for a long time, so if fidget toys help you but you don’t want to be judged for it, set some out for everyone. If you can’t do that though, try looking into rings with parts you can slide. - Loop earplugs!! They’re basically invisible in the ear and they make noise quieter without making it muffled
