Realistically, I probably will be spreading it out over the 5 days rather than doing 3 full days. I guess my plan is to get 3 days of each level completed a week. And then we will do math for 4 days a week instead of 5. Both my son and daughter have some strengths where they fly through different things. So for math and spelling, they are flying through. My kids are to the point that when they write their sentences after they do their spelling list, I only have to write on the board the words they can't already spell rather than the entire sentence. Even with the weekly grammar lesson in Beyond, I rarely write their sentences in full for them to copy. I only write down words they don't know how to spell. Honestly, we only went to this method because they have been writing other stuff, like when they are playing or wanting to write something for my husband, and they do a pretty good job with spelling on there own. So neither one of them are taking as much time in this area. Also, my two younger kids are my 2 children who work really hard to get done quickly. My oldest drags her feet terribly. If this was my oldest and youngest whom I was trying to do Bigger and Beyond with, this would be a disaster! But my middle child, he pushes through anything I give him and with a good attitude. Already, my kids kind of know their schedules and usually these two are pretty much on it and work hard. Before we came to HOD, we had a lot more "workbook" type items we would do for phonics, practicing handwriting, and a few other things. My middle child especially would race his sisters to the table to get done first! He is a little bit competitive. My youngest would also come to the table and she would just work meticulously on her stuff as well. Normally for these two, I am the one telling them they need to take a break because their hands are getting tired - they don't want to take a break because they just want to get it done. And for me - I think that is where the blessing in this family dynamic will be. My son who is moving into Bigger will work so hard until he is done because he knows, once I am done, then I don't have to do anything else for the rest of the day

And he just seems ready.
Plus, I really just need to split everyone up. I need them each to do their own thing. Because my youngest DD is gifted, she can understand anything I give my son. Because she has excellent fine motor skills and is very artsy, everything she does looks better than my son's. However, just because the her stuff looks better than her big brother's stuff doesn't mean that my son did anything wrong. Her stuff will probably ALWAYS look better than my son's. And that is okay!!!! So another big reason that I want to split the two up is because as they get older, I do NOT want anyone comparing themselves to each other in school at all. My son will notice that the things his sister does sometimes looks better. Well, since she is gifted, she does most things better - almost as good as my oldest who is 3 years older. This is not the norm. So I am sure that as my youngest gets older, her handwriting will look better, her art projects will look better, her writing and spelling will be better, and so on and so forth. Again, my son just normal for his age and I think he is on the smarter end when compared with peers. But I just don't want him feeling inferior because he got compared with a child who is gifted and who is really about 3-4 grade levels ahead of her age.
And as for my youngest child who is gifted, there is really no reason to move her up with her brother. She is 6 (just turned 6 yesterday). If she wants to learn more - she can - different building sets and challenges, another language, origami, ancient Chinese writing (that is what the specialist recommended) or just cursive

. But I am not going to move her up. While she can perform the work required in Beyond easily, even if I double it up, you can tell that she is tuckered out after 2.5 hours worth of school. She completes her day well. But I just don't want to put that much "school" on her. I would like for her to be able to sit down and read for fun if she wants, build crazy inventions if she wants (this her passion, making inventions out of legos with moving parts), do mind bender puzzles (she LOVES these), get out the paint supplies and paint a beautiful picture, do word search puzzles (she loves this also and completes adult words search puzzle books regularly). I want just want my youngest to be herself, not stressed about school, and loving learning but loving it away from her brother.
(okay - sorry for my mouthful - these were all the things that went through my head for a couple of weeks before I made the decision to separate my two youngest).
