This file comes with a definition of responsibility as well as a list of ways students can show responsibility in their daily lives. It also includes a worksheet where they can reflect on their own level of responsibility.
This lesson can be adapted for younger grades by discussing the posters first and then responding on the worksheet. The posters can be hung in the classroom for the month that responsibility is the virtue (eg., in a Catholic school).
Please provide feedback! I'm always looking to improve my work :)
