What genre does Andrew Clements prefer to write?

What he personally prefers is only known by him, but what he does write is:

The Jake Drake series, for second and third grade readers, about a boy dealing with the day-to-day of life.

The Seen but not Heard books, of which there are only two.

For the most part, he writes things like Frindle and Lunch Money. I would consider these "true to life" books that look at situations that kids face and presents things that they can relate to easily. Most of his books, however, take whatever the situation is and blow it completely out of proportion. (Example is Frindle).
