I am about to start working at an elementary school. I'll be working with kids 4-11 years old.
Sounds interesting, have you ever been a teacher before?
I have not but did have a lot of choices in schools to work at. There were 92,858 elementary schools in 2001.
Wow, that's a big number.  I wonder how many total students that is.
In 2009 it was estimated almost 3.5 millions students attended school
Is that number in the United States or Worldwide?
Elementary school (United States)
An elementary school is the main point of delivery of primary education in the United States, for children between the ages of 4–11 and coming between pre-kindergarten and secondary education.
In 2001, there were 92,858 elementary schools (68,173 public, 24,685 private) in the United States, a figure which includes all schools that teach students from grade one through grade eight. According to the National Center for Education Statistics, in the fall of 2017 almost 35.6 million students attended public primary schools
