I use this PowerPoint as a introduction of Civics in my 7th grade Civics classes. The information in the PowerPoint correlates with Florida`s Civics:Economics & Geography textbook by McGraw-Hill (2013). It can be found in Chapter 3 of the textbook.
These 19 slides review the following key terms/concepts: immigrants, Civics, citizens, citizenship, law of soil, law of blood, duel citizenship, the Oath of Allegiance, naturalization, aliens(legal, & illegal),denaturalization,expatriation,refugees, and deportation.
I also include many pictures & examples of these key terms/concepts.
