Hidden Graph #MatchMyCL

This is for the #MatchMyCL in March 2021. This activity is meant to be a message encoder. Slide 1: you decide the matrix you want to use to send your message (the person you are sending the message to must also have this matrix). Slide 2: you type in the letters for the message and write down the numbers it gives. Slide 3 will decode a message that you send.
