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.
Students write a message in code using numbers or images to represent different letters. students then send their message to other peers in the class to decode.
