Many of the top 21st century careers require advanced mathematics skills. However, mathematics is a known area of difficulty for students with disabilities (SWD), as they struggle in this area at a higher rate than peers without disabilities (O'Brien, 2016). Mathematical word problems incorporate comprehension of written language, an area known to pose additional challenges for SWD identified as having autism spectrum disorders (ASD; Smith-Myles, Simpson, & Becker, 1995). The authors describe an intervention involving the K-N-W-S graphic organizer, studied for the first time with the intent of examining its effect on mathematical word problem solving of students with ASD. In addition to the background, methods, and results of the current study, the authors discuss implications and future directions of this research.
