Abstract

This research purposes to result teaching material of fractional summation on Indonesia Realistic Mathematic Education (PMRI) basis for class IV of SD N 23 Indralaya and find out dtudent’s in enumerating fractional trough activity from informal to formal. The research subject of class IV SD N 23 Indralaya. Researcher used the methods: Design research ( Gravemaije, 2009) designed in 3 stages, i.e. Front – end analysis and  expert review, teaching expriment and reflection, and assessment and evaluation stage.

For daily evaluation result was 97,96% achievement in summsting the efrction with simelar quotation, 85,71% different quotation 65,21% student,s  achiefement in summating mixed fraction and 83,67% student,s achievement in summating defferent quotation fraction with mixed mix praction.The  student’s assignment result for the first student who reached ≥ KKM was 33 students (67,30%), second assignment  achievement was 38 students (77,66%), the third  assignment achievement was 40 students (81,63%), and the fourth assignment reached 41 students (83,67%) which generally the assignment result was increasing.
