A Tree Grows

As part of a new network adventure called iAnthology (for National Writing Project teachers in the New England/New York area), we are hoping that teachers will share their writing. Of all forms. Including digital compositions.
This morning, I tried my hand at using some photos of a tree at our school as a metaphor for watching my students grow and change over the course of the year.
Does the metaphor work?

Peace (in the leaves of time),
