Have you ever had difficulty illustrating to a class how to read the subdivisions of an inch on a ruler?
Well this file might be your answer.  There are two files in this zipped folder:

• A Smart Notebook File with large images of the giant inch

• Students templates of the giant inch

If you don't have a smartboard, but you do have a way to project the student templates on a white surface you can use the student templates to help your students learn to use a ruler.
