Short answer: Of course not. Many homeschoolers get along just fine with materials they pull together themselves.
And most of the time, they save a lot of money, too. As I've said before, when I was just starting out, it only took one evening of listening to veteran homeschoolers complain about what they spent on curriculum that their kids barely used to convince me to go right to creating my own.
If you're wondering how to get started homeschooling without a curriculum, I've just written a new article with lots of ideas for finding your own learning materials. And don't forget my earlier list of Learning Tools Kids Will Love.
