Teach your students how to encrypt and decrypt binary messages as well as understand binary code. This resource includes a hidden May themed message which students need to decrypt using the key (ASCII Table). Students are also given the option to write their own encrypted binary message.
This is a perfect CS unplugged activity and can be used as an introduction to a lesson, for homework, for early finishers or even when you have no access to computers in the computer lab.
This is an ideal activity for the ISTE Standard of Computational Thinking/
