Sorting networks is an activity that students can do when learning about how data is sorted in technology. This activity from CS unplugged requires students to sort out the networks to create a correct number sequence. To make this lesson more interactive and engaging, teachers could draw the template on a court with chalk and get students to physically participate as a whole class. This will require them to compare data (eg numbers 1-6, height etc) in order to sort network successfully. There will be a “data error/system error” when students incorrectly sort data.
