Let Students Pose the Problems: Active Learning with MathCityMap

This 90-minute online teacher training was developed within the framework of the Erasmus+ project MATRIX and will take place on 10 March 2026 from 3:30 to 5:00 pm (CET) in English via Zoom.

It is aimed at teachers of all educational levels who already use MathCityMap and would like to involve their students more actively in the design of outdoor mathematics tasks. The focus will be on the concept of problem posing as well as a hands-on introduction to MathCityMap student accounts, including the teacher and student views and peer-review features.

In addition to concrete ideas for classroom implementation, the training offers opportunities for international exchange and joint discussion.

Registration is possible until 2 March 2026 by email to Simone Jablonski (simone.jabloski@uni-paderborn.de).

All important information can also be found in the flyer.

We Welcome another New Partner School from Slovakia!

We are happy to welcome the Benkova 34 Elementary School as our new MathCityMap partner school! The teacher Tomáš Kling reports his experiences:

«We conducted one outdoor and two indoor math walks with the students of the seventh grade, each of which include five tasks. The students really enjoyed the tasks, learned how to use a folding ruler, and were able to connect their theoretical knowledge with practical measurements.

The lessons were fun and motivating for the students. We were even more pleased when, at the end of the lesson, we heard from a student who had successfully solved the problem that he enjoyed the lesson and that «at least they weren’t learning,» which we consider a sign that the learning took place naturally and experientially.»

The trails can be accessed via the following codes:
ZŠ Benkova, 7 ročník (Code: 6929692)
ZŠ Benkova, int. I 7 ročník (Code: 1530114)
ZŠ Benkova, Int, II, 7 ročník (Code: 2830250)

We are thankful for the engagement and are looking forward to continuing working together.

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.

We warmly welcome Základná škola Široké as a new partner school of MathCityMap. We are very pleased about the cooperation and the great commitment of the teachers and students.

Three trails have already been created and published. They can be found in the portal under the following titles and codes:

ZŠ Široké – 3628200

ZŠ Široké 2 – 0428201

Široké – 3730018

Teacher Janka Papcunová reports:

«We created the tasks with the students in the schoolyard of our elementary school and in the community of Široké. They really enjoyed both creating the tasks and solving them. Everyone had a lot of fun.

Creating the tasks not only promoted mathematical thinking. It also promoted communication, consideration, and reasoning. We laughed a lot while creating and solving the tasks, and the lessons were very relaxed. Everyone liked that we weren’t in the classroom and didn’t have to sit down.

We also developed additional tasks for students in the lower grades. They were thrilled when they saw that their tasks were being solved by younger students and that they were enjoying it. Some even completed the trails on their own in their free time.»

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.

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:

• 0720464
• 5729484

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.
