One thing that I have loved about homeschooling Alex, is that his imagination has just exploded. I think, for some kids, they need a lot of space to be creative... and public school just really doesn't give you the mental space to do that. Cookie cutter projects that the most creative you can be is to put the wings on your paper cut out butterfly on upside-down. Not that this is all classroom experiences... but many are like this. And the creativity of a lot of children is stunted by this lack of choices.
My favorite thing about this phase he is in is the details. The tiny things that make you realize what he must have been thinking.
What is that? A pen cap? Something he did himself by hand? Neat little details.
