Computer technology is spreading at an unstoppable pace into every part of human life and work. Today, children are getting familiar with new technologies in a different way than adults, because they are growing up with the new challenges. The role of the teacher is to direct students to use information technology creatively and, thus, raise the level of education in general. Today's computer science classes are offered to students as an elective subject in primary schools that meet the technical and personnel requirements. The main goal is to introduce information technology in the coming years as a compulsory subject in the first grade of primary school. Informatics is an ideal area through which children can develop the skills necessary for lifelong learning, such as logical, creative and abstract thinking, creativity, learning by trial and error, upgrading and perfecting their own solutions continuously and using different sources of knowledge. Knowledge and ability to use essential tools and related technology efficiently, are today’s must have skills, as well as possessing a range of skills covering levels from basic programming techniques to advanced problem solving. While today's children are tomorrow’s adults and may not have to be programmers for a living, they will get practical knowledge on how the technology they use actually works and the indicative understanding of what can be achieved with it. One of the tools for initial learning of programming is Scratch, a programming language and development environment for the creation of stories, games, animation, music and other interactive content on the computer, specifically designed to be accessible and interesting to children. This paper will explain how to build applications by programming in Scratch, and the simple examples will be shown through the program structure which consists mainly of graphical blocks that represent commands. Also, the examples included in this paper demonstrate the possibility for use of Scratch with primary schools in certain subjects.
