Dear MathCityMap Community,

In May 2026, the first international MathCityMap meeting for students and teachers will take place in Seville. From May 4 to 9, 2026, teams from different countries will come together to experience exciting math challenges and activities.

The program includes interactive math trails, exciting hands-on workshops and plenty of opportunities to exchange ideas with other students, teachers and the international MathCityMap team. The aim is to discover the diversity of mathematical phenomena in everyday life – all in an inspiring atmosphere.

But how can you take part? It’s simple: we’re looking for the five best videos in which a math trail created by your students is presented. The video should be short, creative and suitable for social media – ideally in such a way that it also inspires and excites others. For inspiration, it’s worth taking a look at our Instagram channel, where you can already see many great examples.

It is also important that your school is one of our partner schools or will become one by July 31. All 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.

The winning teams – each consisting of up to 2 teachers and 6 students – will be invited to the event in Seville. Accommodation and meals for five nights will be fully covered for the participants and 90% of the travel costs (up to €350 per person) will be reimbursed.

The finalised videos can be sent by email to info@mathcitymap.eu by July 31, 2025. The best submissions will also be published on our official platforms and thus become part of our international MathCityMap community.

Be part of this special project, show what your school can do in the field of “outdoor maths” and take the chance to win an unforgettable trip to Seville. We look forward to your creative contributions and to meeting you in person in 2026!

Dear MathCityMap Community,

This Monday, we invite you to a very special Easter egg hunt! The Easter Bunny is known for hiding colorful eggs in the garden, and we’re going on a search to find them. But sometimes, the eggs aren’t so easy to spot – just like mathematics!

Mathematics often shows up in unexpected places in everyday life, just like the hidden eggs. Sometimes, it’s not so obvious how many mathematical puzzles surround us. That’s where MathCityMap comes in: we help make hidden math visible! With our outdoor tasks, you can solve mathematical questions using everyday objects – and do it in a fun and playful way.

So why not start a mathematical Easter egg hunt today? All you need is the MathCityMap app, some measuring tools, and maybe a few friends to join you. Choose a trail nearby and begin your own personal adventure.

To get you in the mood for the adventure, here’s a little puzzle that fits the theme:

The Easter Bunny has prepared 1000 colorful eggs and wants to distribute them in four different nests in the garden. But he has a special challenge:

• The first nest gets 10 more eggs than the second nest.

• The second nest gets 10 fewer eggs than the third nest.

• The fourth nest gets twice as many eggs as the first nest.

How many eggs go in each nest?

We’re looking forward to read your solutions in the comments!

Now you’re ready to solve many more exciting mathematical tasks in the real world with MathCityMap. Have fun puzzling and discovering!

We are very happy to announce a new partner school to be part of our growing MathCityMap network: the primary school in Čeľadince, Slovakia. The teacher Mirka Masaryková brought two creative trails on the school grounds to life and already tested them with her students.

The first trail (code: 8922630) is suited for students of the first and second grade and includes 8 interesting tasks. It was recently tested by 18 students and the teacher reports as follows:

„The pupils in each group worked responsibly, they cooperated and consulted each other, they were able to listen to the opinions of their classmates and worked their way up to solve mathematical problems by talking to each other.“

The second trail (code: 4522629) also includes 8 tasks and was created for third and fourth grade students. It was tested by 13 children.

„The pupils fully focused on individual tasks and were equally actively involved in the process. They cooperated very nicely, measured together, had an individual role each and consulted together on the progress of solving individual tasks.“

With these trails, the students in Čeľadince get to experience how mathematics is not just a subject in school, but also a exciting adventure – one that they can tackle together and where everybody can be part of.

The package with the official partner school badge and the MCM measuring instruments has already been delivered 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 are very pleased to welcome the primary school in Krásno nad Kysucou as a new MathCityMap partner school!

Together with two other teachers, the mathematics teacher Zuzana Tvrdá created three trails for classes 7 and 8 and has already tested them with several classes.

“From the moment we learned about the concept of MathCityMap, trails being used to teach math, we knew we had to try it. It was winter, and we were eager to test this concept, so we set up our first MathCityMap trail in our school library (grade 7 or higher- code: 0918234 ). It was a huge success among our students, and we instantly knew there would be many more trails to come.”

The next trails were located outside of the school.

One trail was created to improve the financial literacy of the students. The trail is suitable from the 8th grade and can be found with the code 4819464.

Another trail served to repeat the content of the 7th grade (code: 1222744).

We look forward to more exciting trails and great new ideas.

We are happy to add a new partner school to our network: the Hodžova Elementary School in Trenčín, Slovakia! This dedicated school has successfully created 15 tasks in four different trails on the school campus. The trails can be found under the following titles:

• ZŠ Hodžova TN I. (Code: 4921511)
• ZŠ Hodžova TN II (Code: 0321510)
• ZŠ Hodžova TN III (Code: 1621509)
• ZŠ Hodžova TN IV (Code: 1221027)

The tasks are designed for students aged 12 to 15 and cover a variety of math topics. These include: area and circumference calculation of square, rectangle and circle, as well as combinatorics, percentages, length measurement, surface and volume calculation of prisms as well as conversion of units of measurement.

The teacher Jana Masariková told us: “The trails were prepared on the school premises in such a way that the pupils can master them during a single lesson. We implemented the trails at the end of the school year, while repeating the curriculum. The children were using their cell phones and worked in small groups. The pupils really enjoyed the math trails. They were enthusiastic and are looking forward to trying the other challenges.”

We look forward to more exciting trails and great new ideas.

We are very pleased to welcome the secondary school Escola Secundaria de Gondomar as a new MathCityMap partner school. Last week we already presented the trail “Gondomath”, which connects heritage with mathematics and was created by a teacher of their school. Due to the great experiences with MathCityMap they created more trails and already tested them.

The teacher Maria João Tinoco told us about two more trails, one inside their school and one outside: The tasks are of wide variety, involving measurements and calculations of perimeter, areas and volume, and also about probabilities, taking advantage of heritage close to the school. The students were very enthusiastic about solving the tasks, which took around one and a half hours.

The trail inside the school can be used from year 9 on:
ESG1, à procura da Matemática! (Code: 3623848)

The trail outside the school is suited for year 12:
Gondomar – Monte Crasto (Code: 0323760)

We look forward to more exciting trails and great new ideas.

Since the end of last year, you can find a new public trail in Gondomar (Portugal), which connects heritage and mathematics. It was created by Maria João Tinoco, who already tested the trail with her students using the MathCityMap App. She has forwarded us the following review:

Mathematics goes out on the street, and it was a success! The trail starts in front of the school, and passes through the lane of Monte Crasto, going up to the Chapel of Santo Isidoro! Everything serves for students to “see” Mathematics and we even had an unexpected visit … after all, our Poet Luís de Camões also “entered” the Mathematics class, as well as several other elements of Gondomar’s heritage. Art, Sculpture, Heritage and … Mathematics on the move at Gondomar Secondary School!

We are delighted to hear about this sucessful mathematics class and the great exploration of the local environment. The Trail „Gondomath“ can be accessed and tested with the Code 1723762.
