I made these posters for my classroom - figured I would share. I'm hoping they help reduce unnecessary interruptions!!
1 finger - "May I use the restroom?"
2 fingers - "May I throw something away?"
3 fingers - "May I sharpen my pencil?"
4 fingers - "May I go get some water?"
Whole hand - I'd like to ask or answer a question!
Enjoy & please rate if you like them! :) Thanks
