New Age rebel in my "Old Age"!

Here we are back at home and I find myself incredibly confused. I am sure I should not be, but nonetheless, here I am. I decided to put the kids in school and went public. It was free (ha), and appeared to be well run and appealing. I allowed those outer appearances to convince me of it's innate goodness. However, Weston is having such trouble or maybe it's me. I can see him coming to this incredible age where the world is opening up to him. He is reading some and is proud of his little self. I am so proud too. He is opening up to the idea of school and is really branching out and I can see him unfolding so beautifully. However, the school in their quest for grades and competition among peers is not going along with this natural state of growth he is in the midst of. Red pens with big red letters are coming home marking up his papers and warning of big tests and grades coming up and his teacher tells me he is just not performing. I beg to differ. He is performing more authentically than his teacher. And I as the parent act concerned, naturally. Then I get angry and wish I had told her what I really feel. Who cares if you grade my first grader, give me a break! Grade him on what? Being a 6 year old individual? It is not that I am against criteria, standards or general necessary education, but come on! Let the kid discover how great learning can be before you stomp all over his little ego. Oh well, we will figure something out!
