Age 7 to 11 Challenge Level:
Here is a table containing all the letters of the alphabet:
It has six rows (going from left to right) and five columns (going from top to bottom). The Vikings communicated in writing by making simple scratches on wood or stones called runes. Sometimes they were written in a secret or coded way. Here is 'was' written in NRICH's coded runes:
Can you work out how the code works using the table of the alphabet?
Here is a message in secret runes:
Can you decipher it?
Perhaps you can make up your own message.
This activity requires some lateral thinking - a bit of fun!
The NRICH Project aims to enrich the mathematical experiences of all learners. To support this aim, members of the
NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to
embed rich mathematical tasks into everyday classroom practice.
