摘要：The aim of this study is to describe students’ minsconception at decimal numbers learning.The research subjects are IV grade students SDN 67 and MIN Tungkob Aceh Besar.Qualitative research method using observation instrument and learning test on decimal numbers material were applied in this tudy.The results of this study is in the form students’ mistakes deccription in understanding the concept of deciding decimal numbers between two integers and change fractions into decimal numbers, and students’ mistakes in solving the addition operation of decimal numbers.It is indicated that the causes of the misconception are sample questions are less varied so that generalizations become wrong and the limited time in using props so students tend to use stackable summation like the summation of integers.
