In the instructive educational process, mathematical activities are very important taking into consideration the tasks that kindergartens seek to pursue, while training and preparing the child for school as well as the influence wielded by this form of activity over the general development of a child. While playing or during his/her day-to-day activities, the child is often put in the position to operate with different quantities of objects or toys, and of course, also to add and subtract or count. At this stage, they don‟t anything else than imitate grown-ups whom they hear using numbers and who wrongly try to teach their children to count ahead of time. Thus, children first come into contact with the external appearance of numbers, with the word, while their signification is gradually assimilated during kindergarten, based on a complex set of actions and operations under the systematic guidance of their kindergarten teacher.
