Networks: Sharing InformationActivities & Teaching Strategies
Students learn best when they can see how ideas connect to their own lives. Plugging devices into a classroom network or passing messages along a string shows information sharing in action, making an abstract concept feel concrete and relevant.
Learning Objectives
- 1Identify devices that can share information within a classroom network.
- 2Compare the process of sharing information directly with sharing it through a network.
- 3Explain how a single printer can be shared by multiple devices.
- 4Predict challenges that arise when sharing information without network connections.

Role Play: Printer Sharing Network
Assign roles as computers, printer, and network hub. Direct sharing group passes paper 'jobs' one by one; network group sends to hub for batch printing. Switch roles and chart time differences on class poster.
Prepare & details
Explain how devices in a classroom can share a single printer.
Facilitation Tip: During the Printer Sharing Network role-play, have students physically stand in lines to represent cables and paths to emphasize how data moves through connections.
Setup: Open space or rearranged desks for scenario staging
Materials: Character cards with backstory and goals, Scenario briefing sheet
String Network: Message Relay
Connect plastic cups with string to mimic network cables between 'devices'. Whisper messages end-to-end and compare clarity to direct shouting. Discuss how networks keep info safe and fast.
Prepare & details
Compare sharing information directly versus sharing it through a network.
Facilitation Tip: While doing the String Network message relay, ask students to predict what will happen if the string is slack or the cups are held at odd angles before testing each change.
Setup: Small tables (4-5 seats each) spread around the room
Materials: Large paper "tablecloths" with questions, Markers (different colors per round), Table host instruction card
Scenario Sort: Direct vs Network
Provide cards with scenarios like sharing a photo or printing homework. Students sort into direct or network piles, then justify choices in pairs. Share and vote as a class.
Prepare & details
Predict the challenges of sharing information without any network connections.
Facilitation Tip: For the Scenario Sort activity, provide mismatched scenarios first so students notice why some situations won’t work before sorting them into the correct groups.
Setup: Small tables (4-5 seats each) spread around the room
Materials: Large paper "tablecloths" with questions, Markers (different colors per round), Table host instruction card
Draw Your Classroom Network
Sketch devices like computers and printer connected by lines or waves. Label sharing paths and predict what happens if a connection breaks. Display drawings for class gallery walk.
Prepare & details
Explain how devices in a classroom can share a single printer.
Facilitation Tip: Ask students to label the parts of their classroom network drawing with words like 'printer,' 'router,' and 'cables' to make the vocabulary stick.
Setup: Small tables (4-5 seats each) spread around the room
Materials: Large paper "tablecloths" with questions, Markers (different colors per round), Table host instruction card
Teaching This Topic
Start with small, everyday examples students know, like sharing a printer, before moving to bigger ideas. Use analogies carefully—students often confuse the model with the real thing. Keep language simple and repeat key terms like 'connect,' 'share,' and 'path' often so they become part of the classroom vocabulary.
What to Expect
Students will show they understand networks by explaining how devices share information, identifying parts of a classroom network, and comparing direct sharing with network sharing in different situations.
These activities are a starting point. A full mission is the experience.
- Complete facilitation script with teacher dialogue
- Printable student materials, ready for class
- Differentiation strategies for every learner
Watch Out for These Misconceptions
Common MisconceptionDuring the String Network: Message Relay, watch for students who believe messages travel instantly through the string without any physical pull or delay.
What to Teach Instead
Have students measure the time it takes for a message to travel along the string. Ask them to change the string tension or length and observe how the speed or clarity changes, making the need for a clear path obvious.
Common MisconceptionDuring the Role Play: Printer Sharing Network, watch for students who think any device can print without following rules.
What to Teach Instead
Give one student the role of 'network manager' who must approve each print job. If a device tries to print without permission or the correct cable, the group should pause and discuss what went wrong.
Common MisconceptionDuring the Scenario Sort: Direct vs Network, watch for students who assume all sharing must use a network.
What to Teach Instead
Provide scenarios where direct sharing is better, like passing a note across a quiet room. Ask students to explain why walking the note might be faster than waiting for the network in those cases.
Assessment Ideas
After Draw Your Classroom Network, give students images of classroom items and have them circle devices that share information and draw lines to show how those devices connect to each other.
During the Role Play: Printer Sharing Network, ask students to compare walking a file to the printer versus sending it through the network. Listen for answers that mention speed, sharing without moving, and what happens if someone else is already printing.
After the String Network: Message Relay, ask students to write one way devices in their classroom share information and one reason why sharing information quickly is helpful.
Extensions & Scaffolding
- Challenge: Ask students to design a network for a new classroom with five devices and write a short explanation of how information will travel between them.
- Scaffolding: For students struggling with the String Network, provide a printed path diagram to place the cups along so they focus on the message movement first.
- Deeper exploration: Introduce the idea of wireless signals by having students research how tablets connect to the school Wi-Fi without wires, then compare to wired networks.
Key Vocabulary
| Network | A group of two or more computers or devices connected together so they can share information and resources. |
| Device | An electronic tool or piece of equipment, such as a computer, tablet, or printer, that can connect to a network. |
| Share | To allow multiple users or devices to access the same information or resource, like a printer or a file. |
| Information | Facts, data, or messages that are sent or received between devices. |
