I usually communicate verbally with his teacher or resource teacher at least on a weekly basis. He is in the third grade.
My child's teacher sends an email each week with the happenings in class and the upcoming tests.
I have never met my children's teachers. However, we correspond as needed via email. I can also monitor any assignments and grades through Jupiter Grades which gives me a good handle on how my child is doing in class and which (if any) subjects are missing assignments.
