Wow! ok, I had to go back to the top, TWICE, to make sure I wasn't on the Accelerated Board and to make sure this said 3rd grade. Y'all sure have some advanced 3rd graders!!! :)
My 3rd grader is using R&S math, just started grade 3 and is only using parts of it.
ETC online phonics.
I just started Adventures in America for history with him and my 7 yo dd.
Science is mostly books and dvds.
I read out loud daily to all my kids.
He reads to me.
ETA: I forgot Song School Spanish. Just the songs, no writing. Nature studies. Kung Fu. Childrens Calvary Bible.
