Make your own worksheets using WorksheetWorks.com . I have only checked out the Mathematics section which looks incredibly comprehensive for a free web-site. Other subjects covered include Handwriting, English, Geography, Thinking Puzzles, and a set of Miscellaneous including such things as graphic organizers, calendars, mazes, etc.
I have found several errors on this website - especially in the mathematics section. It's so sad to look at the answer key and tell my child, "Your answer needs to be corrected" when it is the answer key that is incorrect! As home schoolers, we need to KNOW the answers, not just rely on some website to spew them out for us. We are TEACHERS, after all. We have no credibility if we don't actually understand the material and know the answers our children are seeking.
The bottom line is; We try not to insist on parent-led learning or gravitate toward child-led learning. We try instead to focus on God-led learning and ask for His input and perspective on every aspect of our home school. That way, when others fuss about what Dan and I are doing and make me second guess our decisions -- I can go back to our decision process and find God's fingerprints, reminding me that this is His way.
