The aim of Math4U is to develop mathematical literacy among students in secondary schools, to improve the quality of teaching and student-teacher collaboration, and last but not least to link mathematics education with English and Spanish. In the framework of the project, interactive materials have been created for practicing mathematical curriculum and for more effective work of teachers in preparing tests and exams. 

The main outputs are web applications freely available in five languages - Czech, Slovak, Polish, English and Spanish - on the portal https://math4u.vsb.cz/cs
