Activity: Log on To Code.org U2Ch1L3 - Go to the Internet Simulator - Handout: The Need for Addressing_
This lesson has students completing the same activity three times. Each time students need to create a schedule for the week that allows them to see every other member of their group on one of the days. All intructions can be found on the handout.

• Week 1_"Unplugged": This first unplugged run of the activity gives students a feel for how it runs. This will make sure that any confusion when they get to the Internet Simulator is caused by the lack of identifying information in the simulator.
• Week 2_"Internet Simulator": Login and join a room with your group mates. Once everyone is in the room complete Week 2 on the simulator only...No Talking!
  • When done, on the back of the handout state the problems you faced and solutions you used.
  • Group Discussion: The group should agree on a set of rules they would like to try this time around for how to communicate. Write the rules in the section on the back of the handout.
• Week 3_"Internet Simulator": Login and join a room with your group mates. Once everyone is in the room complete Week 3 on the simulator only...No Talking!
