4my4kids,
Sounds like you’ve definitely got your hands full! Is this your first experience with homeschooling?
If so, and if your school year just began, my first instinct is to encourage you to give yourself and your children some time to get accustomed to the newness. When I first started our home education journey about 18 months ago, I sounded just like you; and I’ve only got 2 kiddos! The first six months was definitely the most difficult, but after much prayer, consistency, and even a few tears, I’m happy to say that we are having so much fun! It was worth all that trouble in the beginning because of the result we are now experiencing! And it will be worth it for you too.
If your school time seems full of interruptions because of the 3yo and 1yo, you might consider doing the subjects which require your complete, undivided attention (like math, beginner reading, copywork) during the younger ones’ nap time.
- If your 3yo seems excited to participate but becomes distracted after a few minutes, redirect her to her own books, blocks on the floor, give her some of her own “workbooks”, crayons or paints, etc. She can still listen in on what you’re doing with the older children, but have something to keep her hands busy.
- You could also provide the 1yo and the 3yo with “school boxes”. Each child would have her own school box with quiet toys, games, or puzzles, special crayons and paper, or whatever else they enjoy, and the box would only be accessible to them during school time.
When we first started, my ds didn’t like copywork either. Instead of starting with lined paper and pencil, we started with a large-lined dry erase board and a fat, dry erase marker. CM recommended new writers begin learning to form letters in the air or in sand with their index finger. We started slowly, learning just one or two letters at a time. Instead of making him write 6 or 8 b’s, I would allow him to write one b, as long as he did it to the best of his ability. I forget which volume CM wrote this in, but she said (and I’m paraphrasing), “Why make a child write the same letter over and over again if he can execute the letter once perfectly?” If my son can make the letter a perfectly (for his age, of course) one time, why should I make him do it five times?
Also we implemented the “Do it nice or do it twice” rule for copywork. I would write out a short sentence, and my ds would have to copy it the very best he could, taking time to make sure each letter looked as closely to my letters as possible. If he did it nicely the first time, he was finished with copywork for the day. If he sped through it messily, he had to do it again. He’s done copywork almost everyday for the last 18 months, and has only had to “do it twice” two or three times.
Your question: “Should I make sure that he is writing his letters correctly or just be glad he knows the way they’re supposed to look?”
- While it is good that he knows how his letters are supposed to look, that’s not the point of copywork. The point of copywork is learning to write beautiful thoughts beautifully. In a gentle, but firm way, you should communicate that he needs to understand that it’s not just about knowing how to make his letters, but how to make them with excellence.
- Copywork is practice. If your ds is just beginning to write with paper and pencil, let him do so on lined paper that’s not too small and with a pencil that fits comfortably in his hand. Make sure he’s holding his pencil correctly. Start small, one or two letters executed perfectly at first. Once he’s comfortable with that, you can begin to add gradually to the amount he’s required to write.
- Breaking his pencil should be discouraged. If my child were to break his pencil out of frustration, we would have to discuss that behavior is not allowed in our home. To me, that’s like a 7yo throwing a fit because he’s not getting his way. If he is frustrated, I expect him to talk calmly with me about it. Perhaps you need to determine whether he’s ready to be writing with a pencil yet or not. It may be that, for now, writing words in sand or cornmeal or flour would be a gentler approach.
Oral narration:
This is also something that takes time. Have you ever tried to narrate something orally? If not, I encourage you to have your husband read a chapter to you and then try to tell him all you know about what he read. It’s not as easy as we think! The first time I ever narrated aloud was at a SCM conference, and I was blown away at how much I forgot and how many details I left out!
Narration is also something that must be developed over time. It is an art and a discipline, and a child cannot be expected to narrate amazingly well his first few times. When your son starts to tell you details from previous days’ stories, explain to him that you’re very impressed at how he can remember things from one day to the next. But also explain that you asked for him to tell you all he knows about today’s story, not yesterday’s. You might also try some of the other narrating techniques and suggestions listed on this site. For example, you could ask your son to draw a picture, dictate his thoughts to you as a list, or build part of the story with his Legos or blocks. If you catch your son recreating or acting out the day’s story in play time, that’s also a form of narration!
You want to help your son avoid crying about his lessons, if possible. CM wanted children to love to learn, and they should! If he starts crying, make sure it’s not his way of trying to get you to end school time for the day. If you have lost your patience with your children in the past, acknowledge it and ask forgiveness and allow the Holy Spirit to teach you patience and gentleness. Lord knows, I’ve had to do that so often! 
I hope at least some of this has been helpful, and I know you’ll receive other great and insightful thoughts and suggestions from more people!
Blessings,
Lindsey
