Hello MS World!
This is the last week we’ll take a deep dive into the Networks and Internet concept from the CSTA K-12 Standards. The third standard is, "Apply multiple methods of encryption to model the secure transmission of information." (Identifier 2-NI-06)
The description is as follows:
Encryption can be as simple as letter substitution or as complicated as modern methods used to secure networks and the Internet. Students should encode and decode messages using a variety of encryption methods, and they should understand the different levels of complexity used to hide or secure information. For example, students could secure messages using methods such as Caesar ciphers or steganography (i.e., hiding messages inside a picture or other data). They can also model more complicated methods, such as public key encryption, through unplugged activities.
In my opinion, encryption is one of the “low hanging fruit” of CS topics. Many kids LOVE solving puzzles! Two years ago for CS Ed Week, my school focused on encryption from pre-K to 12th grade, and there were plenty of accessible activities, videos, and online widgets that made encryption accessible and engaging. There are so many out there! Below is just a SMALL sample of resources:

Do you have any activities, videos, widgets that you use to teach encryption? Please share!
Have a great rest of the week!
