Chelly-
We don't have a 'formal' school day schedule. My kids wake up, eat breakfast, feed and care for their pets, then sit down to school work. We use the School of Tomorrow curriculum, albeit loosely. We do not use EVERY workbook, just the ones that apply to our needs. I like the SOT curriculum because it is a 'self-taught' program, which challenges the kids to learn on their own, by reading and answering questions and doing activities. My kids rarely have to have extra help to master new concepts. This may not be a good choice for kids that have difficulties with reading and comprehension. My 14 year old son is working in the 10-12th grade levels in various subjects, and has an interest in computer programming. I picked up books at Barnes and Noble on these subjects and he is using them to fulfill computer science courses. He has, by reading on his own, learned enough programming in visual basic and C++ to have several games developed and playable. He began this project in February this year with no previous programming knowledge. He is now working on graphics editing, to fine tune the visual aspect. I allow him to work on this whenever he wants, so that when he does, it is enjoyable for him and not something he is forced to do. My 9 year old daughter is also allowed the freedom to work on school work when the mood hits, rather than being forced. My only requirement is that the core subjects get done on a daily basis.
We also don't have a 'formal' school year. We take a couple of months in the summer to just have a 'break' from the core subjects, but I find that they continue on with other subjects simply because it is enjoyable for them. We are very lucky, though, Texas allows home schoolers to basically do as we please. I do keep records of school work completed on a daily basis, projects completed and/or ongoing, and a synopsis of mastered subject material at the 'end' of the year mainly for my own peace of mind, but also in case I ever have to 'prove' my kids are being schooled. I hear other states are not so lenient.
I'd be hard-pressed to say what grade my kids are in, as they both work in different levels in different subjects. They are above state standards in every subject. Last year, my son (then 13) took the Stanford 10 Achievement Tests and scored in the top 1% of the nations high school senior students scores. My daughter also took achievement tests and tested at or above her age level in every subject. This tells me we are on the right track.
The choices on curriculum's vary widely. I am sure you would easily find one that suits your needs. Like us, many families use a hodge-podge of different ones that 'fit' us.
I would suggest googling your state with 'homeschool' or similar terms, maybe your state with 'board of education' to find what your state requirements are.
It is a daunting task when you begin homeschooling, but don't give up! It is not near as tough as it seems, and it is really worth every minute! Lately, we have been brainstorming at the dinner table, creating our own 'lesson plans' for our chicken hatching/raising project (the kids get to hatch a flock of their own). It has been fun planning, and the kids are learning even while doing this...they are thinking through the project, articulating their plans, projecting the outcome and possibilities, and best of all- the 'work' part wont be so 'bad' because they are helping to decide what exactly it will be.
