Another way to go on the cheap and cover your state GLCE's (I worried about that with this year being my first year) for science and history/social studies is studies weekly. If you go to
www.homeschoolstudiesweekly.com you can by the whole package for around $35. My daughters breezed through them and we went on from there but you can pull your state information to see how it measures up. For us it was between 95-100% for those subjects. It was a quick way to help with what I needed to cover. We then took that and expanded everything. My oldest DD even used them as a "review" since she is way ahead there but still loves reading them. They have additional worksheets and test you can print from online for older grades.
Also check out your state department of education website. Ours for example lists all the GLCE's and even has parent friendly versions of math and ELA so you know what you need to cover and can look for materials from your library that fit.
I am now becoming more confident and am relatively sure my children won't be going back/attending more public school so I can deviate from their "schedule".
I think Singapore math and ALEKS math are really big on this site and great for GT kids. We use both very successfully for our kids. Real Science 4 Kids is another and we use that with Studies Weekly. ELA is a tough one here now that my younger girls are progressing at very different levels, so I will be interested to see what people have to say there.
