This photo sent in by Colin Beveridge is not your usual whiteboard! It’s a foldaway portable whiteboard called a Noteboard. Find out more details at http://thisisawesome.co.uk/. Colin was using this to work on a puzzle from MathsJam: “A chopstick (a thin uniform rod) lies at rest in a smooth, hemispherical bowl. The chopstick is longer than the diameter of the bowl. What fraction of the chopstick is inside the bowl?”.
