From the nonprofit organization Common Sense comes this collection of K-12 lesson plans focused on digital citizenship. Originally released in 2010 and updated as of August 2019, this curriculum is "designed to empower students to think critically, behave safely, and participate responsibly in our digital world," which are important skills for any internet user of the 21st century. The lessons address six different areas of digital citizenship: media balance and well-being; privacy and security; digital footprint and identity; relationships and communication; cyberbullying, digital drama, and hate speech; and news and media literacy. The lessons are organized by intended grade level, and each level has multiple engaging lessons that approach relevant topics in an age-appropriate way. For example, lessons for second graders discuss topics such as the importance of device-free moments, what kinds of information are safe to share online, and how to handle online meanness. This research-backed curriculum was developed in collaboration with Project Zero at the Harvard Graduate School of Education. All lessons in the curriculum can be accessed by creating a free account, and lessons include resources such as slides, videos, and downloadable worksheets.
