Yes, something seems very wrong because the child is taking four times as long to do the homework. Generally for kids that young it should be closer to 15 minutes and it's more of a showing the parents what they learned that day then education of a topic. It should be a sheet of paper and a book to read. Now that should take that long, it's probably six questions or activities on that sheet of paper, and most of it is practicing writing. The book should obviously be age appropriate and already in the home. At that age, they're not taking home book assignments. It's the fact that reading to a child is so beneficial that's spending the 10 to 15 minutes to read and age appropriate book helps them.
Opie's child might need additional help or another way to work around doing homework. Clearly, something is not working correctly. It could be that he needs to be fed first and take a nap before doing homework or going to the park and playing for 45 minutes before he can sit down and focus. It could be that the child has ADHD and needs medication because they can not sit still.
Bare minimum the parent needs to contact the teacher informing to inform them that getting homework done is not productive and is taking four times as long as it should be. That teacher should be able to recommend alternatives or needs to accept the boundaries that the child at home can not spend more than 30 minutes on homework every day. If this problem continues without improvement, the next step needs to be scheduling an appointment with the doctor to see if it's a neurological disease or if the child could need glasses or hearing aids.
