Computer literacy and security are not merely elective topics for today’s students. Instead, these have become an essential part of elementary education, starting at the earliest levels— because even preschoolers have access to internet-enabled devices.
Launched in 2004 as a collaboration between the National Cyber Security Alliance and the U.S. Department of Homeland Security, Cybersecurity Awareness Month aims to promote not only awareness of cybersecurity hazards, but also the knowledge and tools users need to protect themselves, their devices, and their networks while accessing the vast information highway that makes modern life possible.
The following cybersecurity lessons, games, and activities cover a wide range of topics and grade levels, and can be implemented in general instruction classes as well as dedicated computer science courses. Nearly all are free, with some requiring a free educator registration.
