Dear MathCityMap Community,

At the end of the year, we would like to look back together with you on an eventful and successful MathCityMap year 2025.

A particularly exciting milestone: the MathCityMap community has once again grown significantly. Around 56,000 users are now using MathCityMap – as in the previous year, this is an increase of about 16,000 compared to the year before. We are very happy about this continuous growth. There has also been a lot of development in terms of content. The number of created tasks has risen to 122,000 – at this time last year, it was still just under 100,000.

2025 was also characterized by numerous workshops and teacher training sessions related to MathCityMap. Many of these were organized by our dedicated partners. In addition, we were present with MathCityMap booths at various events, where we were able to engage directly with teachers, learners, and interested participants.

As part of our Erasmus+ project MATRIX (Math Trails with an Inclusive Perspective on Students Experiences), we were able to implement important new features this year. The read-aloud function and the translation function help to make MathCityMap even more inclusive and to facilitate access for as many learners as possible. With our Content Gallery, we now have a place where we can collect high-quality and diverse public tasks, serving as inspiration for everyone who wants to create new tasks.

Our network continues to grow as well: we were able to gain several new partner schools again and are now working with almost 80 partner schools. This close collaboration is a central building block for the further development of MathCityMap and for the exchange of ideas and experiences from practice.

We are very happy about these impressive developments and the great cooperation with our partner schools as well as our engaged community. Thank you for your interest, your ideas, and your enthusiasm in discovering mathematics in new ways together with us and passing this on. Together, we open up a different perspective on mathematics for many learners and create positive change step by step. Without our amazing users, none of this would be possible – for that, we say from the bottom of our hearts: thank you!

At the end of the year, we wish you and your families happy holidays, a merry Christmas, and a great start to the new year 2026. We are already looking forward to discovering exciting and creative MathCityMap tasks together with you and many new members around the world in the coming year.

Your MathCityMap Team

We are very pleased to welcome the Landesberufsschule für Handwerk und Industrie Bozen as a new MathCityMap partner school. After the school’s teachers participated in a MathCityMap training in 2024, the school has now officially published its first two trails:

The feedback from the students has been very positive. Designed as small outdoor learning activities, the trails offer a welcome change from regular classroom lessons. The spacious area in front of the school and the nearby river provide a pleasant outdoor learning environment.

The trails were carried out with two fourth-year classes from the technical school for computer science as well as a basic vocational class. Equipped with the necessary tools, the groups were able to work independently, with occasional input from the teachers when needed. One important takeaway: a short briefing in the classroom makes the on-site activities run much more smoothly.

Thanks to the frequent double lessons, the trails with their seven tasks can easily be completed within one teaching unit – including travel time there and back.

We thank the Landesberufsschule für Handwerk und Industrie Bozen for their commitment and warmly welcome them to the MathCityMap community!

The package with the official partner school badge and the MCM measuring instruments is on its way and we are looking forward to receiving more applications from all over the world.

All further information on the partner school programme and the requirements for application can be found both in the article on the first MCM partner school and on the homepage of our MaSCE³ project.


On Thursday, December 4th, our third MathCityMap Partner School Meeting took place – once again a very enriching exchange on the use of MathCityMap in the classroom.

This time, the focus was on our new feature, the student accounts. With them, students can independently create their own MCM tasks and thus further develop their problem-solving and problem-posing skills. After an overview of other recent MCM updates and a short introduction, there was a hands-on phase during which participants could try out the new feature directly.

The meeting was attended by part of the MCM team, several project partners, and numerous teachers from Slovakia, Portugal, Spain, Germany, and Italy. Participants took the opportunity to ask many questions. We were particularly pleased with the positive feedback and the valuable suggestions for improvement, which will now be incorporated into the further development of the system.

At the end of the online meeting, we took a group photo to capture this successful event.

We would like to thank all participants and are already looking forward to the next meeting!

On the weekend of September 19–21, there was a festive atmosphere on Frankfurt’s Opernplatz: the Polytechnic Society Foundation celebrated its 20th anniversary—and MathCityMap was there!

It was a special honor for us to be part of these celebrations. The foundation recognized the potential of MathCityMap early on and provided us with active support, especially in the early days. We were therefore all the more delighted to be there with our team.

At our booth, we were able to introduce MathCityMap to numerous visitors – from people who happened to be passing by to math enthusiasts to representatives of other projects. Many were interested and enthusiastic about the idea of learning math outdoors.

Away from our booth, the anniversary celebration also offered a diverse and exciting program: numerous initiatives and projects presented themselves and ensured a varied weekend full of exchange, discoveries, and inspiration.

We would like to thank the Polytechnic Society Foundation for the invitation and support. It was a pleasure to be part of this special celebration!

On Friday, June 13, 2025, Frankfurt’s Riedberg Campus once again became a hotspot for science: the Night of Science opened its doors from 5 p.m. until late into the night – and our MathCityMap team was right in the middle of it all with an interactive stand.

Our outdoor location offered the best conditions for our special hands-on offer: the “Night of Science 25” trail. Equipped with measuring materials, a clipboard and the MathCityMap app, many curious guests embarked on a mathematical discovery tour of the campus. The aim was to solve up to 12 tasks – and to look at everyday places such as stairs, benches or building facades through a mathematical lens.

We were delighted with the consistently positive feedback we received – both from those interested in mathematics and from guests who would not describe themselves as fans of maths.

We would like to thank all visitors for the exciting conversations, the interest and the great interaction. Special thanks also go to the Night of Science organization team for making this unique event possible.

See you next year – we are already looking forward to the Night of Science 2026!
