Year 8 – Lesson 2 – Lights and drums

Learners work in groups through an activity that requires them to encode, transmit, and decode short messages, with each group using a different coding scheme and communication medium (signals, light, sounds, holes on paper, etc.). The activity reinforces the learners’ understanding of text representation using sequences of symbols, while emphasis is placed on distinguishing between symbols and the way in which they are embodied in physical media.
