Identify several local public services and explain that local government organizes and funds them using tax dollars.
A public service is something the government provides for everyone in the community, rather than something you buy just for yourself. Fire departments, police, public libraries, water treatment, road repair, and public parks are all public services.
Public services cost real money to run, and that money mostly comes from taxes -- money that residents and businesses pay to the government. Local government collects some of these taxes and decides, often through the city council's budget, how much to spend on each service every year.
Mastery looks like: They can name several real public services, explain that taxes fund them, and describe one they have personally used.
Common stumbles: Assuming public services are free, rather than understanding that tax dollars pay for them.
