Sounds like the OP is looking at 3rd grade, in which case there are TONS of options. I would also stay away from pre-packaged one-size-fits-all curriculum. One of the great things about homeschooling is the ability to do different levels or methods for each subject and even each different child.My kids are in a different grade in different subjects. I know it can be overwhelming at first, though, and an "everything" curriculum can seem like the best answer. However, with third grade you
really don't need to stress out. Read lots of stuff together, see what she's interested in learning, and try to not to burn out. This can happen if you try to do too much at once or recreate school at home. I'd look at what's out there and take your time. Start with reading and math and then add in other stuff as you go and it seems to fit. At this age it's about not killing that love of learning more than anything else. There's lots out there elsewhere on the internet; obviously there are better boards than Chalkbucket for homeschooling talk. Here are some ideas (just read a little at a time; you do not have to do it all):
Home - Rainbow Resource Center, Inc. (order their print catalog - at over 1000 pages, you're sure to find something to interest you)
Link Removed (an extremely active homeschool curriculum message board based on the classical method of education)
HomeSchoolReviews.com -- Homeschool Curriculum Reviews (reviews of many popular homeschool curricula)
Link Removed (thorough reviews - she does have a Christian slant, but it's not hard to weed through for the secular stuff)
I've used a lot of different curriculum (none of the ones you mentioned, I steer clear of all-inclusive and Christian stuff), so PM me if you have any questions (Story of the World, Singapore Math, RightStart Math, All About Spelling, Royal Fireworks Press Language Arts, Real Science Odyssey, Spelling Power, Sequential Spelling, and many others you can ask me about).
Have fun and enjoy the ride!
