Powers of 10

Wendy Lichtman, a Bay Area author, has a series out called Do the Math: Secrets, Lies and Algebra, and Do the Math: The Writing on the Wall. These are excellent novels that use mathematical metaphors to provide incidental learning. My school in NYC ordered 150 copies and they were gone in a day! The target age range is from 5th-11th grade.
I also wrote an implementation guide available at:

Just click on "For Math Teachers" and the PDF will download. Really easy activities that I have used both in my classroom for 10+ years and have presented around at conferences with reported great success.
