The paper deals with the topic of modern media and how they influence the development of vocabulary in children aged 5 to 7 years. A language-rich environment is crucial for the speech development in children. Children spontaneously develop oral expression in developmental stages as a result of interaction with the environment in which they live. Children need experiential experiences to acquire certain knowledge and skills. They need good language role models so that they can imitate speech and develop language. The first words children learn are simple and contain a small number of letters. As the child grows, their vocabulary expands, and they begin to form simple sentences. When children start connecting words on their own, asking questions is very helpful for their vocabulary development. Language games contribute to the development of speech and language in children, which is why they are popular in educational institutions. There are different types of language games, used according to the needs of the children. Nowadays, given the development of technology and media, games played on computers are becoming increasingly popular. Children are exposed to media and video games from an early age, so it is important to make parents aware of the harmful effects of video games, but also to explain the positive effects and guide them to games that will help their children’s development. Various online language games can be found on the internet and are accessible to everyone. Parents can engage in them with their children at home, and educators can incorporate them into their work with children. At the end of the paper, such games will be described, as well as how the preschool children in one educational group played them. The children were interested in these games and found them enjoyable to play.
