This lesson is an introductory activity to lead your class through discussing essential questions related to civics and government. You should use this early in the year before you've gotten too involved in the curriculum. This will prime your students to think about these issues as they arise throughout the year.
The powerpoint below will guide you through the three essential questions to discuss with your students. For a "Do Now," you should give your students one of these questions to think about and either free write or Think-Pair-Share.
For more thoughts on how to execute the discussion and hit on important points, read this. The key questions are - what is the purpose of government, what does the government owe us and vice versa, and what does it mean to be a good citizen.
There's a summative writing activity at the end that you can use to assess your students takeaways from the discussion. This can either be an exit ticket or a homework assignment.
While this activity can stand alone by itself, it's best done in conjunction with a thematic approach to the curriculum. You can combine this with discussions of essential questions related to economics, equality, conflict, and the movement of people, and refer to these questions in assessments throughout the year.
