Math magic for fourth graders: Discover the Fibonacci sequence in Krefeld!

An exciting initiative for young mathematicians will take place in Krefeld from June 11th to 17th, 2025. The “Mathe-Spurnasen” school laboratory at the University of Duisburg-Essen (UDE) offers fourth-graders the opportunity to engage intensively with mathematics. The aim of the project is to offer children who do not have the opportunity to travel to the UDE a platform for mathematical experiments. This project is supported by the Krefeld School Authority and the Adolf and Margot Koelman Foundation.

In the media library in Krefeld, mathematics educators from the UDE work with the students. Topics covered during this week include Platonic solids, cubes, and the fascinating Fibonacci sequence. In particular, the topic of the Fibonacci sequence is examined from different perspectives, and students explore its meaning and occurrence in nature.

The Fibonacci Sequence: A Mathematical Phenomenon

The Fibonacci sequence, named after the mathematician Leonardo Fibonacci, is an infinite sequence of natural numbers that begins with the values ​​0 and 1. Each number in the sequence is the sum of the previous two numbers and is represented as follows: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 and so on. This particular series of numbers describes many growth processes in nature and is often associated with the golden ratio, a significant proportional relationship. The quotient of consecutive numbers in this sequence approaches the value of approximately 1.618, which is considered particularly harmonious.

In Krefeld, children will learn how these number sequences occur in various aspects of nature, for example in the arrangement of leaves, flowers and fruits. Working with the Fibonacci sequence is not only mathematically interesting, but also aesthetically appealing and promotes a deeper understanding of mathematical relationships.

Additional teaching offerings and future projects

Another important aspect of the “Mathe-Spürnasen mobile” project is the long-term promotion of mathematical learning. A second round is planned for Krefeld in January 2026 to give even more schools and their students the chance to take part in this innovative learning offer. Places in the UDE laboratory are still available to primary school students in the fourth grade during the lecture period if they are geographically closer to the university.

In order to further develop the didactic skills of teachers, the publication “Experiments in Mathematics Classes” from Friedrich Verlag offers valuable materials. The magazine presents ideas and experimental approaches to make mathematics lessons more exciting and accessible. These include topics such as experimental game theory, connections to everyday life and various practical experiments.

Overall, the “Mathe-Spürnasen mobile” project shows how important it is to enable primary school students to engage in active, experimental learning and to present mathematics as a challenging and fascinating subject.
