For teachers
A ready-made teaching resource to explore in one lesson, week by week, or leave on display for everyday learning. No preparation needed.
26 rules that keep
children, teachers and parents safe online.
We've put together an alphabet of simple rules and principlesto help teachers, children and parents navigate the digital world.
Together with the National Pedagogical Institute we distributed it to schools across Czechia.
Now it's interactive too: you can also display it at your school or office.

Questions we hear from headteachers and teachers.
01Can it be used in a lesson?
Yes. Teachers at pilot schools cover a few letters at a time in computing, citizenship or tutor periods. Open the online version on the board and explore it with the class.
02What age group is the alphabet for?
Primarily lower and upper secondary pupils. Younger children can use it with a teacher's help. Some rules (Tor, VPNs, breached accounts) are more advanced, making it a useful tool for discussion, rather than just independent reading.
