Use Velcro-backed visual cards near your tech center so students can signal what they need without asking. Cards show headphones, finished work, login help. Students grab the card that matches their need, you see it at a glance, fewer interruptions.
I love creating visuals that have Velcro on them so they can be used for communication, and then posting them near where students would be needing them. So this would be near your technology center and would include common things that students might need to ask for— if they need headphones, if they want to be done, if they need help logging in. And then students, when they need those things, can easily ask for help.
