Explain why communities and countries make laws, and what could happen without them.
A law is a rule made for a whole community, city, state, or country -- not just for one family or one classroom. Laws exist for the same big reasons family rules do: to keep people safe and to treat people fairly.
Imagine a town with no traffic laws: cars could go any speed, through any red light. It would not take long before that town became unsafe for everyone. Laws help large groups of people live together safely.
Mastery looks like: They can name a real law and explain the safety or fairness reason behind it.
Common stumbles: Thinking laws exist just "to have rules" without connecting each one to a real safety or fairness reason.
