Lesson Idea for students encoding and decoding messages:
Students are taught to write a decoder sheet for the "Pigpen" code.
They write a short message in plain text, and then they re-write it in the Pigpen code.
They they pass the message to a student on the other side of the room, who uses their own decoder sheet to read the message.
This can be incorporated into the learning space as a problem solving station that runs during literacy or numeracy groups.
