NYS-Aligned Standards

9-12.NSD.2 — How data travels across networks via packets, routing, and protocols. 9-12.NSD.4 — How the Internet’s design supports scalability, reliability, and security. NYS Computer Science and Digital Fluency Learning Standards (2020), Networks and System Design

Learning Objectives — “I Can” Statements

  • I can explain how a message is broken into packets and reassembled.
  • I can describe the role of routing and protocols (e.g., TCP/IP) in moving data.
  • I can explain one way the Internet’s design supports reliability or security.

Essential Question

When you send a message, how does it actually travel across the world and arrive intact?

Lesson Sequence

Hook / Warm-Up (8 min)

“Packet relay” unplugged activity: write a sentence, cut it into word “packets,” number them, and pass them across the room out of order. Receiver reassembles using the numbers. Debrief the analogy.

Direct Instruction (15 min)

  1. Define network, packet, routing, protocol.
  2. Walk through the journey: message → split into packets → routed independently → reassembled → protocol (TCP/IP) ensures order and completeness.
  3. Discuss redundancy and reliability: if one route fails, packets take another path.

Guided Practice (18 min)

In groups, students diagram the path of a request (e.g., loading a web page), labeling: device → router → ISP → server → response. They annotate where packets, routing, and protocols come into play, and identify one point where security matters (e.g., HTTPS/encryption).

Share & Synthesis (10 min)

Groups present one diagram; class compares approaches and corrects misconceptions.

Closure (4 min)

Exit ticket: “Explain in 2–3 sentences why breaking data into packets makes the Internet more reliable.”

SDI & Differentiation Block

Supports for MLLs/ELLs

Transitioning/Expanding (NYSESLAT Levels 3–4):

  • Provide a labeled diagram template and a vocabulary card set
  • Vocabulary: network, packet, route, protocol, server, reliability

Expanding/Commanding (NYSESLAT Levels 5–6):

  • Extension: compare packet-switching to circuit-switching and explain the trade-offs
  • Encourage precise networking vocabulary

Supports for Students with IEPs

SDI Adaptation Dimensions: content, methodology, delivery

  • Content: Focus on the packet/reassembly concept; provide a partially completed diagram
  • Methodology: Use the hands-on packet-relay analogy; chunk the journey into labeled steps
  • Delivery: Read aloud; allow diagram-labeling instead of writing; extended time

Suggested Placement: ICT, Resource Room

Teacher Notes

Keep the focus conceptual (the journey and why it’s reliable/secure) rather than requiring memorization of every protocol layer.
