People are aghast that we have no "curriculum". We don't need one. Every single day and hour is working things out, thinking about things, writing, games. He's just soaking this up. He has started playing the piano to play songs he hears and likes (learning the musical scale, sharps, flats). He helps me cook (math, reading, planning, shopping, chemistry). He plays math games, can count change for a dollar, and can do a computer search about something that interests him. He is reading 3rd grade books on his own, and 4th with us to help (he's 6). His writing gets better every day, spelling not so much though

He writes letters to his friends and family. We go to the children's museums, hiking, he's learned to ride his bike after years of resisting. We do yoga and swimming together. He teaches his brother.
We actually sit down and work (if he's game) for a couple hours each day. He is a late riser and gets to sleep until he wakes up and is well rested. He's stopped fighting with his brother and acting out (well, except for normal kid stuff).
Unschooling rocks. We have no idea where we are right now except we know our son and that he is progressing to learn about life.
