For a long time, the period of preschool education was marginalized, and a small number of scientists studied the effects of working with children of that age. Fortunately, lately, the situation has changed a lot. Finally, that period gained in importance as much as it should. If children do not master certain knowledge and skills in some period of life, it is not disputed that they can master all that in some period later, but that way we slow down children's progress. Visualization of activities carried out with children in kindergartens is very important because children learn best when they combine as many senses as possible. Geometric contents are suitable for working with children and there are many creative possibilities for their realization, so it is the obligation of all of us to constantly examine these possibilities and constantly improve them. In the previous period, we conducted a similar research but using applications with models of three-dimensional geometric figures. In this study, the sample consists of 44 children from 3 to 6 years old. The individual approach examined their ability to name and recognize the shapes of two-dimensional geometric figures (circles, squares, rectangles, triangles) through applications using colors (red, yellow, green, purple and blue) to attract children's attention to the offered applications. The answers obtained are important information for further research and important information for the creation of new preschool curricula.
