Honestly, they sound like normal boys. My son tolerates school and I wouldn’t say he enjoys it like my girls all do. He likes to just rush through things and then be free to go do his boy stuff. I try to pick out books that appeal to the boy adventure side. Have you seen this list?

Is narrating the problem, or is it their lack of care? At their age it would be hard to jump in cold turkey with that. Take it in small steps, giving them incentives for trying their best. My son loves his free time, so I reward his best efforts with extra time. If attitude is a problem, then the free time is cut and sometimes Dad needs to come in the picture with some firm, manly encouragement. 🙂
But mainly, try to keep it light right now until their narration starts to improve. There are also some good narration ideas on this site. Give it lots of time, keep a pleasant face with them, and stand your ground that you expect their best efforts.
My son loves that I homeschool him, he tells me that alot…especially when i make some favorite food treats and special lunches for him and the girls. LOL. Remember that our relationships are more important than narration skills, etc. Hang in there and pray, pray, pray for Gods spirit to guide your teaching. He knows what they need already, trust in that. 🙂
