Mathematics learning disabilities (LD) have gained increased attention over
the last decade from both researchers and practitioners. A large percentag
e of students receiving learning disability services experience difficultie
s with mathematics, but little research has examined the specific mathemati
cs behaviors of students with LD who have teacher-identified math weaknesse
s. This study examines the literature on mathematics LD and identifies spec
ific behaviors from that body of research for the purpose of determining th
e extent to which those behaviors are observed in students with LD. Data ar
e presented from observations of 391 special education professionals on 172
4 students with LD, 870 of whom had identified math weaknesses and 854 of w
hom did not. Our results validate the existing literature and provide impli
cations for teachers, researchers, and others interested in studying mathem
atics LD.
