Just over a week ago I shared one of my favourite mathematical puzzles. Today I'm sharing my favourite mathematical game, SET. There is something in this game for young children to mathematics professors. I give SET workshops each year, for Year 8 students up. My slides are here, along with some notes I wrote several years ago. I suggest at … Continue reading The Joy of SET

One of my favourite puzzles of all time comes from Paul Salomon. Paul is one quarter of the Math Munch team, and also makes the most beautiful mathematical art. On Paul's site he calls it ''The Lost in Recursion' Recursion' puzzle. I've retyped his chalkboard photo below: In 2012 I mentored a mathematically-keen Year 11 student. She and … Continue reading Unravelling the ‘Lost in Recursion’ puzzle

Today I want to share a maths puzzle: Is it possible to arrange an entire set of dominoes in a circle so that touching dominoes have adjacent squares with identical numbers? Once you've experimented with a set of dominoes in which the highest number is … Continue reading Connecting the dots
