The present research was conducted with the aim to study the performance of 8th grade students while solving word problems of linear equation emphasizing on Nowman error analysis. . In this research, descriptive-survey method was used, of quantitative type. The statistical universe consisted of 250 girl and boy students studying in Khalkhal school, from which 152 students were selected through two-stage cluster sampling technique and using Cookran's formula. The research instrument consisted of 6 researcher-made questions in addition to interviewing. The validity of questions was confirmed through CVI technique while its reliability was confirmed by employing Cronbach's technique. Research results indicated that the students in both groups (boys and girls) have trifle knowledge in solving word problems of linear equation. They made several mistakes while solving the problems, the highest of which in both groups belonged to reading and under sting of the proems respectively with %69 in boys and %77 in girls.
