communication with teacher first

Better communication with the teacher. It is true that she is not responsible for looking for the homework. Try not be too upset with her tone. Maybe the teacher is not very articulated at how to turning in homework.

My son started K 3 weeks ago. Even he needs to be responsible for bringing back homework, etc. The teacher asks them to line up and open up the folders every day morning before they enter the classroom.

I believe that after one year's train, they are supposed to learn to turn in homework by themselves.
