This web page documents my daughter Autumn’s journey in learning mathematics. See how she reacts to my mathematics questions (mistakes and all) in her very special video blog. If you are a teacher of teachers, please feel free to use the videos in your class. If you are a prospective teacher, watch and try to understand her thinking—you will see her thinking or will want to encourage her thinking in your classes someday.
