Option 2: Describe a classroom activity that involves students encoding and decoding data. You might involve another system that is used to convey information (e.g. Braille, flag systems, sign language, other cultures) or incorporate a resource (e.g. story, song). If you are a teacher trainer, you might describe a professional session for teachers. If you are teaching remotely, let us know how you could teach this online or how you might take an existing activity you have found and adapting for students learning from home.
a classroom activity that students can do is something like this worksheet were they learn to decode the the words behind the message, students can also create their own hidden message and get their friends, family to try and decode it
