Hi H.,
I don't know how old your kids are or if this is the first experience with school so it's a little hard to be specific for me but in general - don't plan too much. It is so easy and it is so exciting to plan and see all the activities and learning that you can do together with your children that it can be very overwelming. There are so many options now and with the internet you will be bombarded with ideas and curriculum.
My oldest of 4 is 19 and we have homeschooled from preschool. It has been quite a journey - I no longer homeschool for a variety of reasons but it was the best thing that we ever did! My kids are very glad that they were homeschooled.
No matter how well you plan things, something may come up. In our family, we had many, many medical problems and one child with a major disability that necessitated many therapy appointments. There were days when no "schooling" got done, but my kids learned about how life really works and how to adjust throughout the day to whatever is thrown at you. They also learned about how much work goes into keeping the household going.
We were fairly unconventional given the hours that we did things and how we put our day together. We did not join a co-op or work with the school district's homeschool section but did a lot in the community and met other homeschoolers that way. There were classes put together by homeschoolers - for instance, one mom had a science teacher and then invited other families to go to their home for science classes. We had a terrific art teacher come to our house and had homeschoolers from the area come to classes. Other than that, we just picked our curriculum ourselves from what we researched and what would work for us.
I can tell you that my kids were very far ahead of their peers in public school even given the lack of a consistant schedule at home. We worked the academics into our day when we could. When my kids entered public school - they adjusted very well socially but did have some problems with the homework as we never had that. We just did the work and were done. Also, the meaningless homework and busy work from school has been difficult for them.
Saxon is the best - I think someone mentioned them already. I love their math program. It is easy to spend way too much money on things that you won't use or things that just aren't right - so be careful of that. So many things look so exciting. Use the library alot - I hardly ever bought story books as we live 2 blocks from our local library and it is a terrific resource.
I can tell you that when my oldest started public school as a Junior in high school, he got straight A's the first year and never opened a book the whole 2 years he was in school (I'm not proud of that fact but it does show how far ahead he was from homeschooling) He then transferred to a community college/construction program and graduated that way. He did like the community college atmostphere much better than high school as the people were more interesting and not "idiotic" like the kids at high school. He did continue to play on the Varsity Baseball team though through school. He started on that as a Freshman even though he was homeschooled.
I hope that helps some. Also, find time for yourself! It is so easy to get so involved in the kids and their education that you forget about yourself.
