Homework fights usually come from uncertainty: when to start, how long it will take, and who is in charge of it.
Same time, same place
Pick a regular start time and a fixed spot. Routine removes the daily negotiation.
Break it into chunks
Write the tasks on a list and tick them off. Short breaks between tasks help younger children reset.
Step back
Be nearby and available, but let them try first. If one subject causes most of the arguments, that’s often where extra help pays off.
