An Assessment of Students’ Proficiency in Using Number Line to Solve Mathematical Problems

Number line is one of the efficient tools for solving mathematical problems; hence it becomes imperative that the proficiency of students in using it be investigated. The aim of this study is to investigate the proficiency of junior secondary school students in the use of number line in solving mathematical tasks. Majority (32.7%) of these students obtained D grade in their respective end of term examinations. The design for the study was quantitative in nature where the data on the students’ proficiency on the use of number line to solve mathematical tasks was collected using questions adapted from [1]. The results from the study indicate that the students obtained an average percentage of success ranging from 45.8% to 50.2% across levels. There was no significant difference in the result obtained by the students across levels. The students performed better on paper and pencil computation at the expense of use of number line.
