The main objectives of the project are to increase the mathematical competencies of secondary school students, provide high-quality prepared materials to mathematics teachers, and improve the language skills of both students and teachers. Specifically, we want to: (1) support students' motivation to learn with real-world examples, (2) strengthen their critical thinking and understanding through "Find the Mistake" tasks, (3) provide opportunities for systematic skills practice using interactive games, (4) increase students' interest in mathematics through competitive activities, and (5) make all materials accessible in multiple languages. Overall, we aim to create a comprehensive, freely accessible, and multilingual portal that will enable both teachers and students to develop knowledge, language, and education at the European level. We want the materials to be usable by bilingual schools, teachers working with international students, and students preparing for international studies. Through free accessibility, we want to enable modern education for everyone without distinction.
Mathematics is one of the pillars of technical and science education. However, it is also a difficult and unpopular subject. Attractive and interactive online materials and applications can improve this situation and increase students' interest not only in mathematics itself but also in studying other STEM fields. According to the Digital Education Action Plan, education systems need to be transformed to be suitable for the emerging digital age. This means, among other things, using new teaching materials and methods and supporting open educational resources. Our goal was to offer teachers and students comprehensive support for all phases of mathematics teaching – from motivation through proper practice of basic skills, support for critical thinking, to competitions and games. We wanted all new materials and applications to be part of the Math4U portal, which was built thanks to the successful projects Math Exercises for You 1 and 2 (2016–2019, 2019–2022) and now serves hundreds of thousands of teachers and students worldwide for practicing secondary school mathematics and serves teachers as a source of materials for lesson preparation.
