Moving Beyond the Page is a secular, literature-based curriculum that offers Language Arts, Science, Social Studies, and Math. Although you can purchase the unit studies independently, we went all in this year and purchased the full set. My oldest is using the Age 9-11 package, while my youngest is using the Age 8-10 package. It's been a while since I've gone with a boxed curriculum, so I'll keep you posted on how it goes.
Although Moving Beyond the Page does include spelling as part of its Language Arts, we are also using Simply Charlotte Mason's Spelling Wisdom. It's a great resource for implementing spelling, dictation, and handwriting into one lesson. It might be worth noting, however, that there are some Bible verses thrown in. We usually just skip over these, as it's definitely the minority of the passages.
We've been with Life of Fred since the beginning and love this unique method of teaching math. You'll find very little rote memorization. Rather, the author uses the intriguing story of a boy named Fred to teach math concepts. It should be noted that this is not a secular curriculum. The author occasionally interjects his Christian worldview into the story. However, it happens infrequently and thus has not been a deterrent to our enjoyment.
In addition to Life of Fred, we are also using Teaching Textbooks to supplement our math curriculum. Ordering the workbook and answer booklet only allows for a much less expensive purchase. Furthermore, it can be worked independently, which I love.
