Four ways to run it
A hall full of children cracking the same message is a very good hour. Four ways to run it, for grades 2 through 5.
Assembly, 45 minutes
The animation on the big screen and one cipher broken live by the whole school.
Class workshop, 90 minutes
Every child writes and breaks their own messages, with the printed sheets to keep.
Half-day capture the flag
A whole grade competing in teams, with a scoreboard and certificates.
Six-week club kit
Everything a teacher needs to run it themselves, one cipher a week.
Ask about a visit
Tell us the grades, how many children and roughly when.
What you get either way
Everything on this site is free and always will be, so a teacher can run the whole thing alone: the animations for the whiteboard, the printable pack, and the challenge board. A visit adds the noise, the teams and the certificates.
