Computation and Word-Problem Errors Among Grade 4 and 5 Students With Mathematics Difficulty

Students with mathematics difficulty (MD) often struggle with both computation and word-problem solving, which are foundational skills emphasized in national standards such as the Common Core State Standards. As most past-error analysis research has primarily focused on a single mathematical topic, little is known about whether students with MD demonstrate error patterns consistently across both computation and word problems. The present study examined error types and consistency that Grade 4 and 5 students with MD made on 22 computation problems and 10 word problems. Using a researcher-developed coding protocol adapted from prior literature, we identified that the most common errors were miscalculation, regrouping subtract smaller integer, and wrong operation in computation; and wrong schema, miscalculation, copy, and regrouping in word problems. The majority of students did not demonstrate overlapping errors.
