Great as a parent-volunteer project or in-class writing activity. Black and white/color options. There's a cover page (to be colored), a "This Is Me" page (for either a 4x6 picture of the child or a crayon/color pencil self-portrait), and a "I Love My Teacher Because..." writing page.
In my son's class, I had the kids work on this during free time... the coloring and writing. Then I came in and glued the pages to a large sheet of construction paper (20x12?) folded in half.

They can be displayed out on the bulletin board or given to the teacher as a gift. Either way, laminating for durability might be a good idea.
