Lol AWESOME. My seven-year-old was talking about how the baby girl already has eggs as she's growing inside me. I think if they talked about anatomy in church class she would have a lot less trouble sitting still there, LOL.
We're finishing up Where the Mountain Meets the Moon, by Grace Lin. So far it's a big hit. They haven't heard many Eastern stories before this but they love it.
LOL my two-year-old thinks the baby will be coming out of my bellybutton. His sisters occasionally try to tell him the anatomically correct version but he isn't interested.
Another vote for MEP! I do need to use the lesson plans often because I'm not mathy either, but it totally makes senes when I read it, and both my dds love it.
So what happens when he does that? I know here, he would be doing his own laundry in the first place, and would be buying a replacement of anything that was ruined in the wash, and if it continued that category of items would be removed from his room for a period of time. (BTDT. It helped a lot.)
We are using BFSU 2, McHenry's Brain, McHenry's Elements, and hopefully McHenry's Cells, plus interest-led days and dissections.
Yeah, it might span 3rd and 4th, lol.
There are curriculum recommendations in TWTM, by the by. :)
I personally combine EVERYTHING, lol, but I haven't done much Montessori. Too much equipment for my taste. I use a bit of the philosophy and that's it.
For lack of effort due to being bored with things being easy, you can do a combination of something very challenging (even extracurricular like a sport he has to really work at) plus following his interests up to his level, like studying anatomy and dissecting a specimen and writing a paper on how the parts he found inside the specimen adapt it to its habitat (for example).
MEP reception might be a bit light for him now. I'd do Miquon and Peggy Kaye's Games for Math and slowly add in MEP 1. My five-year-old is in the middle of MEP 1 now and it's fabulous for mathy kids and building true number sense/understanding plus logic/puzzles.
I read recently about how Amazon is not actually turning a profit with how cheap they are, so maybe they are making moves to try and actually bring in some money? It might backfire, though....
