If your child is reading or doing mathematics below grade level, the homework should reflect this fact. Set a schedule, including both a beginning and an ending time. Most kids need some time to unwind after school before they tackle their homework. Doing it too close to bedtime may make it difficult due to fatigue. Fridays are usually the best day for homework that must be completed over the weekend.
Assignments are still fresh in mind and last minute panic rushes are avoided.
You should help only with that part of the homework your child cannot do independently, such as using flashcards, practicing spelling tests, and clarifying assignments. This builds responsibility and independence in your child. Hold off on watching TV and other fun activities until homework is completed. Provide a home study center for your child with adequate light and few distractions. Also, a dictionary, paper, pens, etc., should be readily available.
