“…What SWLDs struggle with specifically varies from student to student, but given the increasing complexity of mathematical concepts and the language used to describe, teach, and communicate about them in middle school mathematics curricula, it is sensible to address the difficulties in mathematics experienced by SWLDs by addressing their knowledge of mathematical language and vocabulary (Montague et al, 2011;Pierce & Fontaine, 2009;. Middle school students encounter a great deal of mathematical language and vocabulary in textbooks, on assignments and assessments, and in some classroom interactions or instruction (Dunston & Tyminski, 2013;Fuchs et al, 2021;van Garderen, 2008;Witzel et al, 2013). Word problems, perhaps the most frequently encountered problem type on mathematics assessments, demand not just knowledge of mathematics operations but also text comprehension (Fuchs et al, 2015;.…”
