Thanks for the response!
i would only advise to research the uk curriculum, it is available for free download in uk on gov.uk it is long and gives all info regarding current status of learning expected within each stage,
This is mainly where I was looking for just some place good to start to figure out what we're getting ourselves into and something to help us get organized if we start to move forward.
If you know of the site for the US for homeschooling expectations let me know, if not I'm sure I can find the information after a quick google search.
