Back of Book:
6 has a problem.
Everyone knows that 7 is always after him. Word on the street is that 7 ate 9. If that’s true, 6’s days are numbered. Lucky for him, Private I is on the case. But the facts just don’t add up.
Will Private I put two and two together and solve the problem . . . or is 6 next in line to be subtracted?
This is a great book to introduce mystery genera to a classroom. Children will love reading about the private I who is investigating the mystery of how 7 ate 9. This book is filled with math puns and jokes that are on each page of the story. Readers will enjoy following Private I as he figures out what happens to number 9. Lazar is a fantastic author and her concept is quite brilliant. MacDonald is a talented author, who brings the numbers to life. This is a story that can be used for multiple unit studies. I can see myself using this as a writing prompt for my students. I highly recommend this story.
Ages 7 and up
