Miss Little's Gift

Miss Little's Gift by Douglas Wood, illustrated by Jim Burke, Candlewick Press, 2009, ISBN 978-0-7636-1686-1
Tells the author's own study of battling ADHA as a child, and of the patient teacher who helped him learn to read. It's all about "the importance of the right book at the right time, and ...the impact of a good teacher." (book jacket)
By the way, the "right book at the right time" for Douglas was The Little Island by Golden MacDonald (a pseudonym for Margaret Wise Brown), which was first published in 1946. It won the Caldecott Medal for Leonard Weisgard's illustrations.

Mr. Ouchy's First Day

Mr. Ouchy's First Day by B.G. Hennessy, illustrated by Paul Meisel, G.P. Putnam's Sons, 2006, ISBN 0-399-24248-1
PS: Mr. Ouchy, a new teacher, is nervous about his first day of school, but when he teaches the class about time and counting, they all enjoy the experience.
This would make a great book to read on the first day of school. Good section about goals for the year.

The Junkyard Wonders

The Junkyard Wonders by Patricia Polacco, Philomel Books, 2010, ISBN 978-0-399-25078-1
PS: Inspired by a teacher who believes each of them is a genius, a class of special-needs students invents something that could convince the whole school they are justifiably proud to be "Junkyard Wonders".
Oh my, Patricia Polacco has done it again. In the spirit of Thank You Mr. Falker, Polacco tells the autobiographical story of yet another inspiring teacher. As a young girl, Polacco finds herself in the "special class", known around school as the Junkyard. She makes genuine friends, is truly happy, and is encouraged and inspired by her teacher, Mrs. Peterson.

My Teacher for President by Kay Winters

My Teacher for President by Kay Winters, illustrated by Denise Brunkus, Puffin Books, 2004, ISBN 0-525-47186-3
PS: A second-grader writes a television station with reasons why his teacher would make a good president, but only if she can continue teaching till the end of the year.
This is a wonderful book: while describing his teacher's qualifications for president, the student also describes a president's job. Illustrations cleverly show what is meant by each duty and how each person carries it out. (It's amazing how similar the two jobs are!!). Reminds me of the old quote: "A teacher's job is to take a bunch of live wires and make sure they are grounded."
