Exit Ticket

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.

QUESTION 1
Name one secure online habit and one risky one.
For example, using a strong unique password (secure) versus reusing one password everywhere (risky).
QUESTION 2
Why does two-factor authentication make an account safer?
It adds a second step to prove it is really you, so a stolen password alone is not enough to get in.
QUESTION 3
How can you spot a phishing message?
It often creates urgency, comes unexpectedly, and asks you to click a link or share information; check the sender and do not click.

Create: a security checklist.

Have students list their online accounts, write the secure habits each one needs, and turn them into a personal security checklist. A printable online-security worksheet is in the Computer Science library.
