The app is available in many different languages!
MathCityMap is based on the math trail idea introduced in Melbourne, Australia in 1984 (that time on paper only). Since that time lots of mathematicians and math educators have picked up this fascinating idea. Just like us. Additionally we set a new approach to this project using mobile technology.

The MathCityMap App for smartphones is developed for students who would like to walk a math trail during school lessons or even for interested users who want to explore their surroundings with a mathematical point of view. The app leads the user via GPS to the mathematical tasks of a chosen math trail and gives automaticaly feedback on the answers of the user. In addition the app also provides hints in case someone is lost on a certain problem.

The MathCityMap web portal is for teachers and creative minds who want to create tasks and trails. Good tasks will be made public and can be used by everyone to combine them with their own tasks for a personal math trail. Furthermore the public tasks can inspire users for their own tasks. All created math trails can be solved by walking with a smartphone or can be printed out from an automatically generated PDF file. The web portal also provides tutorials how to get started, publications in the field of math trails and general informations about doing mathematics outdoors.


Version 2.2.3

• The start view includes now a search bar on the top of the view. This search bar allows you to filter existing trails by name, code or city.
• The info view of a trail now displays also information “About this trail”. This field is usually used by trail authors to provide a short description on what the trail is about.
• If the automatic validation of answers within a trail is disabled, the app now offers a possibility for users to manually complete a task by clicking the “Complete” button. The app then displays the next task.
• Fixed bugs:
o When entering a trail code, the app will now always open the info view of this trail.
o After solving a task, the next task will be displayed automatically as expected.
