Hi A.! I don't use an all inclusive curriculum.
For language skills I use Sing Spell Read and Write. I started with this in K and will probably use it until 3rd (my son is in 2nd grade now.)
Math- I love Math-U-See. I won't use anything else, it's THAT good.
History/ Geography- We use Galloping the Globe
Science- Apologia
Foreign language- Hands down, I would choose Rosetta Stone.
Good luck!
