I am homeschooling my 8 year old daughter and I am trying to teach her the basics of US government. One topic that I want to cover is the need to Federal, State and Local governments.
I already established the premise that one of the basic functions of government is to establish laws and provide services. And that some laws pertain to all people in the US, some only to those in our state, and some only those in our county. Similarly there are some services, like national defense, that the Federal government provides, and some services like state colleges that the state provides and some services like police, school and libraries that the county provides.
But I still feel this definition is lacking. Is there anything that can be added to help her understand why we need these three "levels" of government?
