The aim of the thesis is to create a prototype of a web application based on the teaching method of mathematics created by professor Milan Hejný for children of the first grade (4th grade). This method works with visual elements to help students learn primarily logical thinking and mathematical principles. In particular, tasks and explanations of calculating fractions will be covered. The application will be based on Professor Hejný's textbooks and will therefore be able to fulfill the function of supplementary teaching material.

Study the previous math app and evaluate its usability and user-friendliness.
Incorporate interactive and gaming elements in the app design.. Create friendly graphic design and UI and UX. In addition to verbal assignments, test other assignment mediation options in digital medium. Explain the possibilities of a web solution using examples from this application. The functionality and visually designed application will be demonstrated in the form of a prototype in the Figma program.

The application prototype will be consulted with the teacher for the first grade.
