摘要：AbstractEducational activities aimed at improvement of conceptions in first class at the elementary schools embody mainly in the process of assigning the numerical information to different number conceptions. We realized teacher experiment with the 6 and 7 years old children attending the first class at the elementary school. We explored the level of their number conceptions and the ability to use them. For the realization of the experiment we chose number 3, because it is the number from the numerical scope 1-10 and as it is freely distributed in fairy tales, advertisements and other areas of ordinary life. Children were asked to draw what they imagine, when we say number “three”. We pursued the ability of children to assign the specific model to a given number. Children were asked to arrange the pictures into groups according to some similarity and to explain their choice. Thus the mental maps of children concerning their images of number three were created. Children created the fairytale with number 3 from their models.
