So they can reinforce and practice skills they’ve already learned, and so teachers can assess a student’s mastery of the information. That’s also why parents should not do the homework for their kid.

Ask prodding questions, lead them to the answer, but don’t give it to them. It’s OK for a kindergartner to write an S backward; don’t fix it.

Homework is a child’s independent study, and it should stay that way. But parents can give other assistance: assign a space with few distractions, establish a strict time for homework, make the child explain the teacher’s expectations.

Get a clean sheet of paper and work on [a similar task], but don’t redo the homework.

Don’t express your distaste for a particular subject. And help draw up a timeline so they learn to handle deadlines. The whole idea is to create a sense of discipline and order.
