Here is the Transum collection of mathematical riddles to make you think outside the box then enjoy the satisfaction finding the answer brings.

A riddle is a statement, possibly with a double or hidden meaning, presented as a puzzle to be solved. Riddles are of two types: enigmas and conundrums, but all of the riddles collected here have a mathematical connection. Posing riddles is an old and respected way of describing mathematical situations, connections and problems.

There is definitely a place for mathematical riddles in the Maths classroom. They can be used as lesson starters or finishers. They could be presented to pupils to think about for homework or included in the school newsletter to promote mathematics.
