Chess in education preschool education received the first class of students of mathematics the primary effect on skills

This research has aimed to examine the effects of chess education, which has taken at preschool education, to mathematic skills of primary school first grade pupils.In Sakarya province, Özel Şahin Primary Schools' 42 first grade pupil has formed of the working group of this research. According as the general purpose of the research, experimental group has consisted of 22 pupils (11 girls and 11 boys) who have educated in chess at nursery school and control group has been included 20 first grade pupil (13 girls and 7 boys) , who were choosen randomly. Final test with a control grup is the model of this research.While gathering data for the research, ''Satranç Bilgisi Anket Formu'' has used for scaling pupils' basic chess knowledge and ?Erken Matematik Yeteneği Testi-3 (TEMA-3)? ,which validity and reliability workout has made by Erdoğan and Baran (2006), has used.Data analysis using SPSS 12 package program was carried out in computer environment. Frequency and per cent range for variables of demographic features were used for analyzing gathered data in the research. Moreover, to examine the validty reliablity of the test, KR-20 test was used for computing the test' consistency coefficient. Re-test correlation coefficient has helped for evalueting the test if it gives consistent measurements or not depend on time. Mann Whitney U-Test has provide to control the validity of scale. Also % 27 - top % 27 material analyzing process has being used.Research results show that chess educated pupils has had higher mathematic skill points (U=119.5, p<0.05). They have answered more question in mathematic test correctly and have had high points (U=117.5, p<0.05). When looked at the reliability range values, pupils had performed due their age or better than expected (U=121.5, p<0.05) In addition to these, they had got high points from 'Chess knowledge survey forum (U=210, p<0.05).Chess player pupils analyze results in section B.22 and section B.44 of 'Erken Matematik Testi-3 show that they have performed better than non-chess player pupils in such cases as having a mental number lineer in one digit numbers and writing in two digit numbers, counting in big numbers after accumulation, displaying of variation feature of operation in addition symbolically, having a mental number lineer in two digit numbers, counting of objects one by one from 11 to 20 and subtracting small number from big number or subtracting numbers from theirselves in one digit numbers.These results show that chess education at preschool has a positive influence on pupils' mathematic skills.Key Words: Pre-school education, mathematics, math skills, chess.
