Explain the concept of specialization -- people focusing on one kind of job and trading for what they need -- and identify several community jobs and their specialties.
Imagine if every family had to grow all its own food, build its own house, sew its own clothes, and teach its own children everything, all alone. That would be exhausting, and most families would not be very good at most of those jobs. Instead, communities use specialization: each person focuses on getting really good at ONE kind of job, and trades money or goods for everything else needed.
A farmer specializes in growing food. A baker specializes in turning flour into bread. A teacher specializes in helping students learn. Because each person focuses on one specialty instead of doing everything, the whole community ends up with better food, better bread, and better-taught students than if everyone tried to do everything alone.
Mastery looks like: They can explain specialization in their own words and name at least two real specialized community jobs.
Common stumbles: Thinking specialization means doing MORE jobs, rather than focusing on and mastering just one.
