Driven by the Directorate General for Tourism in collaboration with Casio, the project focuses on education, sustainability, and tourism decentralisation. Each route begins at the Generalitat's local tourist office, where participants can pick up the map and a Casio scientific calculator. From there, the city becomes a mathematical game board inviting exploration with a curious and analytical eye. The itineraries pass through iconic landmarks and unique corners, emphasising concepts such as geometry, proportions, symmetry, and logical reasoning. Along the route, participants will need to solve challenges designed for different difficulty levels. Each route is inspired by the career of a Catalan female mathematician connected to the city and is accompanied by an original illustration by a local artist. Mathematical routes across Catalonia with a name of their own The mathematicians featured in these routes have not only stood out for their talent and career, but also share a direct link with the city where each itinerary unfolds. This connection adds a more personal and meaningful dimension to the experience, while also giving visibility to the role of women in science. Barcelona — Mathematical route dedicated to Carme Torras, with illustrations by Cinta Arribas. An international reference in social robotics and artificial intelligence, and also a writer of science fiction literature. Girona — Mathematical itinerary through Girona featuring Maria Antònia Canals, illustrated by Srta M. A mathematics educator with an outstanding career in teaching and didactics, especially linked to the city of Girona. Tarragona — Mathematical route through the city linked to Maria Bras-Amorós, with artwork by Carmen Segovia Moreno. Professor at Rovira i Virgili University and expert in coding and cryptography. Tortosa — Family-friendly mathematical route in tribute to Griselda Pascual i Xufré, with illustration by Míriam Rivera Iglesias. A secondary school teacher, author of mathematics textbooks, and a key figure in the educational reform of mathematics in the 20th century. Lleida — Featuring Eva Miranda Galcerán, with work by Lily Brick. A mathematician awarded the prestigious François Deruyts Prize, specialising in differential geometry and mathematical physics. This mathematical route offers a new way to discover Lleida. How to take part? Taking part in a mathematical route is as easy as visiting the tourist office, collecting the materials, and starting the adventure. The activity can be done in groups or independently, and it’s a great way to explore the city in an active, fun, and different way. Maths becomes a tool to understand the space around us rather than an abstract concept. An experience for the whole family These routes are especially designed for young people and teenagers, but are also ideal for families. The self-guided format allows the pace to be adapted according to age and interest, and each challenge can be solved collaboratively. It’s a fun activity that stimulates logical thinking, communication, and observation. Moreover, the routes connect with emblematic sites that often go unnoticed, enriching the visit and encouraging visitors to view urban heritage from a new perspective. In this sense, they are also a great option for schools, summer camps, and educational organisations looking for activities outside the classroom. This project is part of a growing range of family tourism experiences in Catalonia, offering age-appropriate activities focused on educational, responsible, and enriching leisure. A proposal with values These routes not only promote critical thinking and meaningful learning, but also highlight female scientific talent from our region. They also encourage sustainable, educational, and decentralised tourism, inviting visitors to explore cities beyond the usual tourist circuits. In short, they are a way to reclaim science as part of everyday culture and the urban landscape.
