The Hady application is educational software designed for children in the 1st grade of elementary school. It is based on the principles of the Hejné method - a modern approach to learning mathematics that emphasizes discovery, logic and the joy of solving problems. In the application, children work with the Hady environment, which is aimed at practicing basic mathematical operations - addition, subtraction, multiplication and division.

The environment is divided into thematic levels, the difficulty of which gradually increases. Each level is designed to motivate children to progress further and at the same time allow them to create their own mental models of the solution. The application uses the power of technology - tasks are generated dynamically, they are diverse and the child can adapt them to their own needs.

Playful graphics, simple controls and game elements make math fun. Children do not even realize that they are learning - they enjoy solving problems and at the same time naturally develop their mathematical thinking.

The goal is to support a positive relationship with mathematics from an early age and to make quality education available to every child. The application is suitable as a supplement to classical teaching or as home practice. It is also ideal for parents or teachers who are looking for a modern and effective way to introduce mathematics to children.
