This resource contains an unplugged activity to model how home networks work. It builds up to increasingly more complex networks, adding in details such as routers, wifi access points and the internet along the way. The lesson plan contains links to the Progression Pathways documentation, and differentiation ideas for delivering the content. The presentation takes students through, building increasingly complex networks (by adding to the previous network) using cards and connectors to model the network. The resources for these cards are included at the end of the Presentation. The activity finishes with a model of a network and some vocabulary, the students are then asked to tell the story of how a data packet moves from one device to another across the network using all of the vocabulary, listed. There is a focus throughout on the Computational Thinking ideas of Abstraction and Decomposition.
