Who is behind the Maths Box?

Hello! My name is Jörn. I am 57 years old, live with my family in Bremen and have been working as a primary school teacher for over 25 years. I studied mathematics and sports at the University of Bremen – two subjects that perfectly demonstrate how important movement, enjoyment and curiosity are when learning.
As a teacher, father of two children and someone who has been standing in front of a classroom for decades, I know that
children learn mathematics best through play – and with a strong understanding of numbers.
It is not simply memorising tasks that leads to long-term success, but understanding numbers, quantities and relationships.
These experiences motivated me to develop Mathekiste. I wanted to create a maths app that helps preschool and primary school children discover maths without pressure – lovingly designed, didactically sound and entirely geared towards child-centred learning.
Today, I am delighted when Mathekiste helps children, parents and teachers to
experience mathematics with joy, motivation and confidence.

Why playful learning is so important to me
More than 25 years of experience teaching mathematics
Daily work with children in the number range up to 20
Focus on number concepts, understanding quantities and basic calculation strategies
Conviction: Enjoyment of learning is the basis for lasting success
