Binary coding – unplugged CT

I have been creating lots of resources lately and have been trialling them with students in classes. This latest one is an unplugged Computational Thinking activity that illustrates to students how images are encoded into binary and sent over the internet and then rendered into an image on the receiving computer. The students emulate this by calling out their code to each other, one encoding their image design into binary and calling out the binary code to the receiver to reassemble the image and then error check.

This student is doing the high resolution challenge and is making a QR code to then encode to send to another student
