I really want to encourage you so that you know that are not alone.
Lately - this recent year has become a really tough year for me. I work from home and over the past 3 months, my workload feels like it has doubled

. Needless to say, this has impacted my school day. For me, I just take one day at time. With my oldest, she has been starting her guides on the youngest end of the age range. However, she is not a fast reader and sometimes the volume can wear her down. So recently, she approached me about completing something that I knew would take up a bunch of time. I have decided to let her go half speed for school for two months. It has been great! This will help give her a little bit more time before she gets to the next guide. Plus, it has helped cut down on my teacher time that she needs. For my son, he is doing Bigger. Well, this week, I have had report after report and task after task to complete. I have been getting up at 5:00 AM most days (today I woke up at 3:00 because I accidentally fell asleep at 10:00 last night) and I work until lunch or later. This week I looked straight at my precious baby boy and said, "Sam, can you read this (history and science)? I have a lot of work today. If it is too much, I will do it with you later. But if you can help me, I would really appreciate it." And guess what, he did it! And he did it well, too!!!! I was so proud. Yesterday he even had vocabulary words that he needed to look up. Usually I have to sit at the table with him the WHOLE time and encourage/help him as he moves along. He even did this alone! My youngest is an excellent reader - she can read 4th or 5th grade level books easily. She decided last week she was tired of waiting for me so she has been taking her guide and completing all of her work alone. She actually is so interested in working alone that she is doing more than one days worth on occasion. I told her I don't mind as long as she does every box starting with the left side of the guide, working to the right and then she has to start with the left again. But she is my worker bee and I think she just wants to get done with the year LOL.
My encouragement to you is that when I need it, God bless my kids to help me. I wonder if you approached your 8 year old and propositioned some shared responsibilities? I know you mentioned she could read the history. Would it be a struggle for her? There was a time period with each of my kids were they could do things but it would be hard and then they could do things like this and it wasn't so hard. I don't know which phase your dd is in. If it would be a challenge for her to read it, then I wouldn't have her do it. But if it would be easy, she is a fast reader, and she enjoys reading, then I would let her do it. Also - there is always a subject or two (or item or two) in the guide that my kids hate doing. My youngest this year has to copy poetry every day from the Beyond guide. She hates it. My son hates doing the weekly vocabulary activities. And my oldest dd hates written narrations. Oh well - they have to do it anyway

We all have things we do in our lives we may not like but we deal with it. I also have used several other curriculums before finding HOD and this is by far the most fun and interesting curriculum (that is academically sound) that I have found. Other curriculums seemed to have too much busy work, not enough instructions, not enough skill building, boring activities, boring books, unbalanced days, to much time teacher time, etc. For me, HOD may have activities in it that kids might not like but at least with each activities, their is a skill or point to it. Over all, my kids have enjoyed it for the most part. I personally love it because I love the academic growth and achievements I see in my kids. As a bonus, they seem to genuinely like it overall.
If it were me, next week I would take the week off. I would set up a schedule that you think you could follow consistently. I would account for things like fatigue or times when your kids need a break. I would schedule her day and schedule the independence items she needs to complete alone. Until you get to Preparing, your kids won't be overly independent. I made a note book up for my younger two kids to follow and I write down their daily independent items in it. They each have a table that they can sit it and work on written school work. And they each have all of their school stuff at their fingertips at all times. For my son, he studies AWANA, plays the piano, math, notebooking items in the Bigger guide, reads 20-30 min per day (we will be starting DITHOR in a week or two though), cursive and math alone. He just checks the box when he is done. For my youngest, she does AWANA, piano, copy poem, math, reads and cursive alone. She also just checks the box. For my oldest, she is a dawdler so I don't know if this would have worked for her or not. At her age, I just give her the guide. But she isn't quite as task oriented as my younger 2 who seem to really thrive with this method.
As for everyone doing something together, I think that she may sense exhaustion in you and has come to feel that her opinion on her choice of school materials is now debatable. This is just my humble opinion so please disregard as I mean absolutely no offense. I am only sharing with you what has happened to me in the past. I have gone through seasons where I am exhausted and where I feel completely discouraged. My kids then have seen this in me and they start becoming listless too. They see school activities as debatable. And then I engage. Oh no! It is just a downward spiral. When I came to HOD last year, I researched it a ton and prayed over it. I finally selected it October (because the curriculum I had before just wasn't a good fit). I was so worried about using it and my school day because I have found that I too become overwhelmed with my life and then my school gets thrown to the wayside. When we first started with HOD, there were things my oldest really didn't want to do. I could have modified the guide but after praying about it, I didn't. Basically, if the guide said to do xyz, then you will do xyz. Were there times of complaining? Yes. Were there times of anger? Yes. Were there times of outburst with consequences? You guess it, yes.

But in the end, I was so glad I persevered as the mom, stuck my ground, and had my kids do what the guide says. I no longer have nearly as much bucking and complaining. My days are very balanced and consistent now. My kids know what to expect. And it isn't debatable, I refuse to engage! This was completely freeing for me. Is everyday wonderful now....uhm, no. But in general, life is so much better. The kids have a fairly set schedule. They have an expectation for how their day will go and what will be expected of them. And they know, that if the guides say to do something, they know we will do it. For me, school no longer gets thrown by the wayside. I believe in what and how I am teaching the kids. I love the resources. And for the most part, my kids seem happy too.
I will say a prayer for you for wisdom. You are in a tough spot. I also saw that you use other products for learning in some areas. You can always still use those products and use HOD for other subjects. But one last thing I wanted to mention is that now that I have switched everyone over to only HOD products (last year I used a separate math and separate spelling along with separate phonics for my middle child), I now feel like my day is balanced and smooth. I do still include Latin in our day, but other than that, we use all other subjects according to the HOD recommendations. I feel like this has helped tremendously because my kids no longer feel overwhelmed by what is asked in the guide since they aren't duplicating any of that elsewhere. For example, if you are doing a different language arts program, there may be a lot of writing in both HOD and that program. As kids move up in level, they start reading everything to themselves for history and science. And that can then create even more of an unbalanced day. My last item is that at the end of the this coming school year, I would pray about whether or your daughter is actually placed correctly. If she places in Bigger, I move her up. Bigger is more work but if she is bored with Beyond, maybe she needs more of a challenge. Because placement is key to having a successful year, having her in the right guide will help with her attitude on the work. So again, would assess whether or not your dd is actually placed solidly in Beyond and go from there when you start your next school year.
