Trying to get her to log in to her Maths zoom lesson. She screamed at me and kicked me exceptionally hard with boots on. I am shaking with anger and pain. I have left her to do her maths lesson alone (usually supervise). This is a red line for me. it is written in our house rules and on our house whiteboard (I left her DF for breaking my jaw). What can I do to convey to her how unacceptable this is?
