This research is backgrounded by the low ability in counting 1-20 related to calculation and diminution. It is proven by the result of doing the enrichment exercises which was done by 20 students in a class but only 5 students who got BHS score (Berkembang Sesuai Harapan) in the indicator of mentioning calculation result. Therefore, the objective of this research is to know the use of funnel calculation media in order to increase the ability in counting 1-20 for the students of Kindergarten Muslimat Wonocolo Surabaya, and to know the raising ability in counting 1-20 by using the funnel calculation media related to calculation and diminution. The research design which is used in this research is action research by using Kurt Lewin model. It consists of pre-cycle, cycle I, cycle II and reflection. The participant of this research is 20 students of B-1 group at TK Muslimat Wonocolo Surabaya. The action research of Lewin Kurt model consists of 4 stages; planning, implementation, observation and reflection. The results of this research are: 1) The use of funnel calculation goes well in cycle I. It can be seen in the activity of the students which enthusiastic in using funnel calculation media. Besides, the observation result of the teachers and students get the score in the percentage of 63,09%. It also can be seen from the activity of the teachers and students which rises by getting the score of 79,76% with the increase in 6,65. 2) There is an increasing of the ability in calculating 1-20 which is proven by the raising of the score after using funnel calculating media in cycle I in amount of 63,74% and the cycle II in amount of 76,87% by the increasing in the percentage of 13,13.

Growth (growth) is an increase in the size of various organs that can be measured by the size of weight (grams, kilograms) or length (centimeters, meters). Development (development) is the increase in the ability or expertise in the structure and function of the body more complex, in an orderly pattern, as a result of the process of maturation. Keep in mind that the growth and development of each individual is unique. This is caused by several factors including genetic factors (heredity), environment (whether biological or psychological) and behavior (state / behavior in the family). For optimal growth and development of children, the environment must be considered, it must support the biological and psychological health of children, nutrition, must be sufficient and balanced, regularity to health services includes, providing immunization, rest and sleep must be sufficient and avoid fatigue. By using the content analysis method and documentary study, this research seeks to describe the meaning of early childhood growth and development stimulation in physical and mental perspectives. Appropriate stimulation will further optimize multi aspects in children, especially in terms of physical and mental.
