If your child is consistently not completing homework on time, it's important to address the issue promptly to help them develop good study habits and responsibility. Here are some steps you can take:

1. Identify the underlying cause: Talk to your child to understand why they are not completing homework on time. It could be due to a lack of understanding of the material, poor time management skills, distractions, or other issues. Identifying the underlying cause can help you address the root of the problem.

2. Set clear expectations: Establish clear expectations with your child regarding homework completion. Discuss the importance of completing homework on time, and set specific expectations for when and how homework should be done. Make sure your child understands the consequences of not completing homework on time, such as lower grades or loss of privileges.

3. Create a conducive study environment: Ensure that your child has a quiet, well-lit, and distraction-free study environment at home. Provide them with necessary study materials, such as textbooks, notebooks, and pens, to help them stay focused and organized.

4. Teach time management skills: Help your child develop effective time management skills by setting a regular study schedule and allocating specific time for homework each day. Encourage them to prioritize their tasks, break down larger assignments into smaller, manageable chunks, and set deadlines for each task.

5. Provide support and guidance: Offer your child support and guidance in completing their homework. Help them with difficult concepts or provide guidance on how to approach assignments. However, it's important to strike a balance between supporting them and allowing them to develop independence and responsibility.

6. Encourage self-motivation: Foster intrinsic motivation in your child by helping them understand the value and purpose of homework. Encourage them to take ownership of their learning and set their own goals for completing homework on time.

7. Communicate with teachers: Stay in touch with your child's teachers to understand their homework assignments, due dates, and expectations. If your child is consistently struggling with homework completion, communicate with the teachers to seek their support and work together to find solutions.

8. Provide consequences: If your child consistently fails to complete homework on time, it may be necessary to implement consequences, such as loss of privileges or other appropriate consequences. However, it's important to use consequences as a tool for learning and improvement, rather than punishment.

Remember to approach the situation with patience and understanding, and work together with your child to develop good homework habits. Each child is different, and it may take time to find strategies that work best for your child's unique needs and learning style.
