Eight-year-olds do not get tricked because they are careless. They get tricked because a message is written to feel urgent, and nobody has shown them the trick. This 12-page printable unit shows them, in words a grade 3 reader can hold: six real-looking messages to judge, one page they keep, and a script for telling an adult.

No devices, no logins, no accounts. Nothing about any child is collected, and no child has to admit anything to take part.

What is included (12 pages, US Letter, print-ready PDF)

• Cover, contents, and the one-sentence goal of the unit
• Teacher page: how to open it without shaming anyone, prep checklist, a 40-45 minute timing table, and a 20-minute fallback
• Hook: “Maya wins a free skin” — the class judges one message together
• The tool: The Five Bites, with cut-out badges that stay on their desk
• Worked example: read it slowly, once, tick the bites, name the next step
• Six case cards for pairs: a game prize, a gift-card text from “Mom”, a school-office email, a pop-up, fan mail — and one card that is genuinely real
• Secrets sort: usually okay / only with a grown-up helping / never shared, plus the three-sentence tell-an-adult script and where to report
• Partner talk (passing allowed), “My own rule”, and an exit ticket
• Answer sheet, expected sorts, differentiation, and a cut-out letter home to families

How to use it

Print one copy of pages 3-11 per pair and a badge strip per student. The hook runs as a whole class, the tool is one page they keep, and the six cards do the teaching while you listen to the arguments. It fits a 40-45 minute advisory or computer-science lesson and splits into two shorter sessions. The 20-minute fallback on the teacher page covers a rainy lunch-in or a last-period slot.

Why one of the six cards is real

Half of these units fail, because children conclude that everything online is a lie and stop reporting the ones that matter. Card F is a genuine message. The class has to argue for it. That argument is the lesson.

Safe to teach

No indecent content, no links for children to click, no scary imagery, and no activity that asks a child to reveal anything about themselves. The reporting routes are the public ones (in-app Report, ReportFraud.ftc.gov, NCMEC CyberTipline, 988) and they are printed for the adult, not the child. The teacher page states plainly: if a student discloses something that has already happened, this lesson is not the place to handle it — follow your school’s safeguarding procedure.

A note on how this was made

I set the scope, the reading level, the six messages and the answers, and checked every page against what actually happens in a class of eight-year-olds. AI tools helped me draft layout and tidy text; the teaching decisions are mine. If a page is wrong for your students, tell me — I edit resources after teacher feedback.
