For Languages Arts we are still testing the waters. We used worksheets at one point that my oldest hated. This year we tried Simply Charlotte Mason's Using Language Well and Spelling Wisdom. I really love both of these but would like to try the Brave Writer program next year because it incorporates lessons with the books you are reading, a practice I'm sure will work well for our family.
We have found great success in reading using the Explode the Code Program. We have never had to go further than book 3, but I'm sure the later books in the program are just as wonderful.
