@sim IDK if you are religious (if so, not all of these will be appealing) but some commonly used curriculum in the homeschool community is Abeka, Math U See, Teaching Textbooks, and Sonlight.
There's also the HSLDA, which helps people make sure they can homeschool legally.
@sim Ah, okay. I suppose the HSLDA would not apply then, that's an American organization.
Most Christian curriculums for math (like Math U See) doesn't have any ideological overtones at all, but a lot of other subjects like History and English do, so I would look out for that.
@sim nvm; the HSLDA has international resources as well!
