This paper presents a more detailed account of the stages of development of children's drawing. Already at an early age, children come into contact with drawing. They start with doodling, which give they a sense of comfort by drawing different lines. In the drawing phase, children develop their motor and visual coordination. In the next phase, the phase of expression with complex symbols, considerable progress can be seen. The child begins to draw in more detail, uses more complex symbols, and particularly shows progress in drawing a person. Man is not shown as a head-legs, but also a body. At this stage, the child includes thought operations that guide the hand in expressing an idea. The next stage of development of children's drawing is the stage of intellectual realism. In this phase, the child becomes bolder in his ideas, which leads him to interesting art creations. The characteristics of this phase are transparency, representation of action in phases of movement, emotional proportion, polyperspective, folding and unfolding of forms, inverted and vertical perspective. The last stage is the stage of visual realism. During this stage, the artistic expression of the child begins to resemble the expression of adults. Some of the characteristics of this phase are coloristic, atmospheric and geometric perspective. In addition to providing a detailed description of the stages of children's drawing, this work also provides an analysis of children's works. During the analysis of the works, we tried to see which phase of children's drawing the students belong to and what are the characteristics of the completed drawings. The task set for the students was to draw their family at the meal/table with a pencil from memory. The goal of the research was to observe the differences in the artistic expression of first and third grade students by drawing the same motif with a pencil (family at the table). The tasks of the research were to observe with regard to the stage of children's artistic expression, what is the artistic expression of children in the first grade, to observe with regard to the stage of children's artistic expression of artistic expression, what is the artistic expression of children in the third grade, to compare the artistic works of children in the first and third grade and to notice the differences in artistic expression with regard to the age of the children.
