100,000 tasks!

Congratulations, MathCityMap community!

We’ve reached a major milestone: the MathCityMap portal now includes an incredible 100,000 math problems from around the world!

Each task is proof of how math is out there in the real world: whether calculating surfaces in the city, finding angles on statues or determining opening hours at the playground. MathCityMap makes it possible to experience and understand mathematics in a practical way.

We would like to present a few tasks from recent years here:

From 2019: Europe-Fountain (Code: 148310) for year 8

There is a fountain with a figure of Europe on the market square. The pedestal on which the figure is enthroned forms a regular polygon. How many degrees does each of the interior angles of this regular polygon have?

From 2020: Places of Interest (Code: 7817388) for year 7

On this information board is a map with a grid and blue and yellow spots representing different places of interest. What percentage of these spots are in the two squares of the map where the church is shown?

From the year 2021: Stairs (Code: 1324003) for year

How many ways are there to walk up the stairs if you can take one or two steps per step? The step sequences can be combined.

From the year 2022: Playing in August (Code: 4847292) for year 5

This information board shows the opening hours of the playground. These change throughout the year. How many hours a day is the playground open longer in August than in November?

From the year 2023: Poster (Code: 1975801) for year 7

What is the maximum number of posters that can be hung in the area marked in blue if a poster measures 65 cm x 65 cm? The posters must not overlap.

From the year 2024: The U in Art (Code: 5685281) for year 10

The sculpture “Blickwechsel” is located on the climate art trail on Eckweg. Determine the volume of the letter “U”. Enter the volume in cubic centimeters as an integer.

Without the support of our dedicated community, reaching this milestone would not have been possible. Teachers, students, math enthusiasts and many others have enriched the portal with their ideas. Every single task contributes to making mathematics more accessible, exciting and understandable for everyone.
