I used to want to be an elementary school teacher.  There are over 92 thousand elementary schools in the US
That is a ton of schools, teaching would be a rewarding job, do they get paid much?
I am not sure about the average salary.  But with 3.5 million students in elementary school, I would imagine the job demand is pretty good
That is a ton of students! Have elementary schools been around for a long time?
They have.  It consists mainly to focus on a balance of academics and socialization skills.  
I see, what kind of academic skills do they focus on?
Often, they focus on basic math, basic grammar and spelling, and other subjects
Those are things everyone needs to learn! Do they still have music class and gym class?
Depending on the state, they have physical development, arts, and social studies
