Students are also typically introduced to the concept of [[social studies]], with an emphasis on establishing ideas of history or [[civics]] in either a personal or larger sense. Some states focus on the basics of [[US history]] and [[patriotism]], with a focus on the [[Founding Fathers of the United States|Founding Fathers]] and the time period surrounding the [[American Revolution]]; other states require social studies focus on family relationships in first grade, leaving community, state, and national studies to higher grades.
