Easy Peasy All-in-One
A free, online homeschool curriculum created by Lee Giles. It curates lessons and links from across the web and stitches them into a daily plan. Parents follow a daily schedule that sends the child to various external websites and resources.
You have a tight budget, are comfortable with a piecemeal experience that pulls content from many sites, and don't mind that some links go stale over time.
You want a single, internally consistent curriculum with original lessons designed to work together, and you'd rather print than click.
