This eTwinning project's main objective is to promote the development of computational thinking among participating students. Computational thinking is an essential skill in the world. Current digital technology, which involves the ability to solve problems logically and creatively, using concepts and strategies related to computing. During the project, students will be encouraged to identify everyday objects and situations so that computational thinking can be applied. They will be challenged to matte analytical problems. Mathematicians and find solutions using algorithms and logical reasoning. One of the proposed activities will be the use of GeoGebra, an online tool that allows you to explore mathematical concepts in an interactive way. Students will have the opportunity to create and manipulate graphs, solve equations and explore geometric properties, thus developing their computational thinking skills. Additionally, students will be encouraged to create physical or online games that involve logical and mathematical challenges. This activity will allow them to apply the concepts learned in a practical way and creative, encouraging collaboration and critical thinking. Throughout the project, students will have the opportunity to connect with other students from different countries, sharing their experiences and results This will promote the exchange of ideas and mutual enrichment, as well as developing communication and teamwork skills. At the end of the project, students will have gained a deeper understanding of computational thinking and its practical applications They will also have developed problem-solving, critical thinking and creativity skills, which are fundamental to success in the constantly evolving digital world. This eTwinning project offers a unique opportunity for students to explore computational thinking in a practical and meaningful way, preparing them for the challenges of the 21st century.
