Private by default: what not to share

Groups sort information cards into fine to type, think first and never, learning that what they type into apps and chatbots may be stored and seen by others.

Students will be able to

  • sort personal information by how risky it is to share
  • explain that what you type into an app or chatbot may be stored and read later
  • name information they should never share online, such as passwords and OTP codes
  • know to ask a trusted adult when unsure

Prepare

  • One set of 12 information cards per group (see the activity)
  • Three headings on the board: "Fine to type", "Think first" and "Never"
  • Tape or magnets for the board
  • One worksheet per student

Words to know

Personal information:
Facts about you that could identify you or be used to find or copy you.
OTP code:
A one-time code sent by text or an app to confirm a login or a payment. Only you should ever see it.
Stored:
Saved on a company's computers, sometimes for a long time, where staff or other systems may see it.

Main activity · Unplugged: paper and pens

Fine, think first, or never?

Groups sort cards such as your full name and school, your home address, a photo of your ID card, a password, an OTP code, your favourite food and a homework question into three piles. Disagreements about the middle pile show that privacy depends on who could see it and what they could do with it.

Warm-up7 min

Who could read this?

  • Ask: "When you type a message to a chatbot, who can read it?" Take quick answers.
  • Explain that many apps save what you type. Company staff may review some of it, and it may be used to train future AI.
  • Introduce the rule for today: private by default. Share only what the task really needs.
Activity18 min

Sort the cards

  • Hand out the cards: full name and school, home address, a photo of your ID card, a password, an OTP code, your favourite food, a homework question, your phone number, a photo of a friend, a parent's bank card number, a story you wrote, a worry about your health.
  • Groups sort for 8 minutes into fine to type, think first and never.
  • Each group puts one card on the board and gives a reason.
  • Agree on the never pile: home address, ID card photo, password, OTP code, bank card number.
  • Discuss the think first pile: name and school, phone number, a photo of a friend (ask them first), a health worry (better to tell a trusted adult).
Practice15 min

Clean up the message

  • Students complete the worksheet, including rewriting a message to remove private details.
  • Ask two pairs to read their cleaned-up message aloud. Check that the chatbot could still help.
  • Talk about what to do if you already shared something: tell a parent or teacher, change the password, and do not panic.
Wrap-up5 min

Private by default

  • Ask: "Who is one adult you could ask if you are not sure?" Each student thinks of one name.
  • Write on the board: if it is in the never pile, it never goes online.
  • Hand out the exit ticket.

Teacher tips

  • Use made-up names and addresses in every example. Never ask students to write their real personal details on the worksheet or the board.
  • Misconception: "deleting a message removes it". A deleted message may still be saved by the company or seen by someone already. That is why the never pile matters.
  • Some students may have shared things already. Keep the tone calm: the fix is to tell an adult and change passwords, and nobody is in trouble for asking.

Exit ticket answers

  1. Why is it a bad idea to type your home address into a chatbot? A good answer: What you type may be stored and seen by other people or systems. An address shows where you live, and it cannot be changed like a password.
  2. Which of these should you never share online? C. An OTP code
  3. You are not sure whether something is safe to share. What is the best first step? A. Ask a parent, teacher or another trusted adult

Think about who could see what you type. Decide what is safe to share.

  1. 1Tick one column for each piece of information.

    InformationFine to typeThink firstNever
    My favourite food
    My password
    My full name and school
    A photo of my ID card
    A maths question from homework
    An OTP code sent to my phone

  2. 2Rewrite this message so it has no private details but the chatbot can still help: "Hi, I'm Lan from class 7A at Lê Lợi school, I live at 12 Trần Phú street. Can you help me write a birthday card for my mum?"

  3. 3A website asks for an OTP code to give you free game coins. What should you do?

    • Type the code quickly before it runs out
    • Never share it, close the page and tell an adult
    • Send the code to a friend to check
    • Share it only if the website looks nice

  4. 4Why should you ask a friend before you upload a photo of them anywhere, including an AI app?

  5. 5Name a trusted adult you could ask if you are unsure what to share, and write what you would say to them.
