So I am going to start posting EMPOWERMENT tips for y'all!
First tip to empower your students to have more control over class is to allow your student the power to initiate a quiet signal.
We do this with the lights in my room. Any student, at any point can turn one light off if they feel the class is being too noisy!
It is way more meaningful when it comes from the students and it is one less thing I have to remind them of!
