A Major Milestone: 50,000 Users on MathCityMap

We are thrilled to celebrate an exciting milestone: MathCityMap has officially welcomed its 50,000th registered user! Meet Marvin Ahmed, a 19-year-old student at the Technical University Braunschweig, who is studying Mathematics and Biology with the goal of becoming a teacher. In this article, Marvin shares his journey with MathCityMap, his experiences, and what excites him most about using the platform.

Marvin came across MathCityMap through a university seminar titled “Didaktik der Geometrie” (Didactics of Geometry). During the seminar, the MCM project was introduced as a tool for making mathematics more tangible and engaging for students.
“MCM was presented to us as a way to make math more accessible and tangible for students, enabling them to get in touch with math in another, more fun way!”
What made the introduction especially memorable for Marvin was the hands-on demonstration by our team member Simon Barlovits, who guided students through the platform and answered questions live.

As part of the seminar, Marvin and his group—proudly named “Sons of Pythagoras”—were tasked with creating their own math trails. They quickly learned how challenging it can be to design problems that are not only solvable and accurate but also clearly understandable for all students.
“For me, the hardest part was: How do you formulate a task so understandably that everyone can actually grasp what they are supposed to do, and you don’t make it too easy?” This hands-on process gave Marvin a new appreciation for the intricacies of task design—a skill that will serve him well in his future teaching career.
 

Marvin’s debut task on MathCityMap, titled “So viele Möglichkeiten!”, taught him valuable lessons about real-world variability and precision in task creation.
“I didn’t formulate the task well enough, so many things could have been misinterpreted…”
Despite the challenges, Marvin was proud of the outcome and grateful for what he learned.

He sees great potential in using MCM in his future lessons:
“I really like MCM and will definitely use it in my lessons later on. I think it can make the teaching of some topics in math, like the calculation of volumes, much more interesting and fun!”

We’re honored to welcome Marvin as our 50,000th user and are excited to see how he — and thousands of other teachers, students and math enthusiasts — will continue to use MathCityMap to bring mathematics to life. To Marvin: thank you for being part of our community. And to all our users — here’s to the next 50,000!
