How the internet sends data
Explain that the internet is a network of networks and that data is broken into small packets, addressed, sent along different routes and reassembled at its destination
Lesson
Set out your lesson
“How the internet sends data means practising the idea at the table with a simple screen-free or sandbox check. We will demo once, then your child tries.”
Bring to the table
- Device photo cards or a labeled computer sketch
- Sticky notes for part names
Extra for the adult
Worked example. The keyboard is an input — it sends letters into the computer.
Optional challenge. For How the internet sends data, add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples How the internet sends data, not mastery.

How the internet sends data means practising the idea at the table with a simple screen-free or sandbox check. We will demo once, then your child tries.
Materials: Device photo cards or a labeled computer sketch; Sticky notes for part names. 1. Say the goal of How the internet sends data in plain words once. 2. Adult points to one part (input/output/storage/processor) and names its job. 3. Child labels three parts and says the job of each in plain words. 4. Fresh check: one fresh part-and-job match. Record and stop. Done: three correct labels with a job sentence each. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Explain that the internet connects millions of smaller networks around the world
- Act out sending a message as packets: split a sentence into numbered cards, pass them by different routes and reassemble them in order
- Describe what happens when a packet is lost or arrives late (e.g. a video call freezes) and how numbering helps rebuild the message
“Could your child explain why a video call sometimes freezes — that the internet chops data into little packets that travel separately and are put back together?”
