Welcome to Mathelona and our unique series of number puzzles which are now available in pocket book format.


Like many new ideas, our popular number puzzle started life on scraps of paper and nearly became a wooden board game many years ago, but eventually it progressed to become an app in 2011.

It now regularly appears as one of the daily challenges at our number puzzle page as well as being posted on Twitter.

The Mathelona Pocket Book

MathelonaPBookCoverOur very latest publication is our Mathelona pocket book of holiday challenges.

The first in our series, Vol.1, contains 28 different number puzzles and has primarily been designed for children to use at home, ideally with parental involvement, to improve their arithmetic skills.

Our challenges are perfect to sharpen logic skills, concentration and resilience.  They are, of course, also attractive as a good test for the puzzle enthusiast.

A typical Mathelona challenge can be seen below.

The Mathelona pocket book is a useful travel companion on long journeys in the car, bus, train and aeroplane.  The challenges are also great to try during holiday periods so children can keep on top of their mathematical thinking, whether it be in the caravan, at the holiday cottage, on the beach or by the pool.

Skills Required

mathelonabookThis type of arithmetical exercise is perfect for children (and adults) aged 7 years and above as it is essential they have a good basic knowledge of the four operations when progressing through primary school.

Mathelona reinforces this in a fun and challenging way, you will undoubtedly see children’s skills improve the more challenges they try.  This traditional method of learning also enables confidence and creativity to flourish throughout their educational life.

Private Tuition Sessions

It’s also strongly advised that private maths tutors use Mathelona as part of their sessions, either as a fun starter, confidence-building exercise or even as part of a diagnostic screening procedure. Tutors have learned so much about their students when observing them tackling the various challenges.
