Th roughout the month of October, the Oban High School maths department has been running the Oban Number Challenge to test pupils’ numeracy skills.
Posters showing a set of numbers have been placed throughout the school and in various locations around Oban itself, with the simple question: what do these numbers all have in common?
You can enter using the QR code found on the posters – extra consideration is given to those who can also say how many of these numbers there are!
