 Enlarge On Beyond a Million: An Amazing Math JourneyAuthor: David M. SchwartzIllustrator: Paul MeiselPublisher: Dragonfly BooksCopyright: 1999ISBN: 0-385-32217-8Number of Pages: 32Ohio Standards Alignment: Grades 6–10This book provides a context for exploring extremely large numbers, including googol and beyond. Students involved in popping popcorn for an assembly have a popcorn machine that is out of control, and they are curious to find out the number of kernels popped.  Since it is impossible to count fast enough, Professor X suggests “power counting” using powers of 10 to do the job.  Many interesting facts involving large quantities emerge along the way.

 How to Use This Book Read the story to launch a middle grades lesson on exponents, large numbers, and infinity. This book could be assigned in the upper grades as an entertaining introduction to rules for exponents and scientific notation.
 Highlights and Insights This book promotes number sense and allows students to learn about the use of exponents, powers of 10, and scientific notation in a way that appeals to them. The factoids provided as side information serve to show that large numbers are not isolated entities, but have applications in the real world. Vocabulary development is promoted when the names of large numbers are accurately given (e.g., quindecillion) instead of the generic references used in many books. The reference to months of the year can spark some cross-curricular discussion when students investigate why the ninth month is named September.
