Continuous improvement of conditions in which children grow and learn is an imperative for all of us. The youngest ones, children of preschool age, deserve special care and attention. Adequate stimulation of their learning, creative environment, motivating educators and everyone around them are crucial factors that shape the development of many young children, as well as influence their desire for further learning and exploring. In order to gather all indicators that tell us about the ways children learn, their success, the way they understand their environment, continuous research is required. However, doing the direct research with such young children is often challenging, since they often cannot understand well if they know something or not, and if they do not want something, they don’t say it easily. It is why we decided to do a case study in kindergartens in Sarajevo with mixed groups. The sample was 40 children, aged 3 to 6 years. With individual approach, we researched their abilities to recognise and name solid geometric figures (ball, cube, cylinder and cuboid) using applications and colouring (red, yellow, green and blue) in order to have children’s attention on given tasks. The responses that we received represent important information for further research and creating new curricula for preschool education.
