Introduction: Children should finish the fundamental motor skills in order to achieve the motor competencies. Especially, if they intend to achieve manipulative competencies, hand- eye coordination.
Methodology: In the year 2013(1392), 12000 elementary school students in four districts of Karaj, Alborz province, 64 seven- to- eleven (7-11) children were selected randomly, then classified in two control and experimental group. In pre-test and post- test, the test coordination of both hands of Peg Board (Bimanual pegboard), the test of simple reaction time for variable reaction time, and the modified soda pop test for variable eye- hand coordination were given. The experimental group practiced cup stacking for 16 session while the control group did not have any practice during this time. In this study, SPSS version 20 for data, the analysis of variance 2 combination of 4×2 for data analysis, and Mann- Whitney test were used.
Cup Stacking: Too much attempt has been made in the implementation of this exercise to arrange (set) and collect (clear) the cups in a certain order.
Results: the results of this study demonstrated a significant influence of cup stacking exercise on the eye- hand coordination of eight & nine year’s old children.
Also had a significant effect on the coordination of both hands of nine & ten year’s old children. Meanwhile, had a significant effect on the reaction time seven, nine and ten year’s old children
Discussion: The results indicate that play with cup stacking has a positive effect on reaction time. Research on eye hand coordination show that, Also this exercise are effective on the eye-hand coordination. The impact on the coordination of both hands and both sides of the brain activity in areas of cognitive improvement in concentration, problem solving and learning better, and this study shows the impact of the play with cup stacking on cognitive skills – behavioral.
