01
Set up the session
Ten minutes of movement first. One task on the table, everything else out of sight. A visible timer, and an agreed finish point that does not depend on quality.
Sit alongside for the first two minutes. Task initiation is the hardest part, and company through it is more useful than checking afterwards.
02
Protect the relationship
Agree with the school what a reasonable amount of homework time looks like, and stop at that point with a note rather than pushing to tears.
You are not the teacher. Your job is the conditions, not the curriculum.
