Information on taxes 10-12. can be explained to the class in the form of educational games, which they will remember much more than just learning the general theoretical material. Research object: The level of knowledge and understanding of taxes among high school students. Research subjects – educational games and materials about taxes (for older students.) The aim of the authors is to evaluate how the understanding of the importance of taxes in the country and society among senior students could be improved if educational games and materials about taxes were used in the learning process.
