Differentiation

Pupils needing extra support: If real world networks are too abstract, work as part of a guided group with adult support, using the school network with the pictures and string that you looked at as a group last time, and make a table model of the school network. Work through traffic light role play with reading support.

 

Pupils working at greater depth: Should add in other variables to their network, such as more traffic lights, the supermarket, updating the database as well as the till, the drive-thru, passing information to the cooks and food packers, different transactions at the bank.
