About 5% to 10% of school-age children have been identified as having mathematics disabilities (Fuchs, Fuchs, & Hollenbeck, 2007), and students whose math performance was ranked at or below the 20th to 35th percentile are often considered at risk for learning disabilities or for having learning difficulties in mathematics (LDM; Bryant et al., 2011; Fuchs et al., 2007). Students with LDM lag behind their peers beginning in early elementary school and continue to fall further behind as they transition from elementary to secondary school. According to National Assessment of Educational Progress (NAEP; 2015) mathematics assessment data, during the past 10 years, score gains were seen at Grades 4 and 8 for higher performing students at the 75th and 90th percentiles, but there were no significant changes over the same period for lower performing students. For instance, according to fourth-grade NAEP mathematic achievement data, the percentage of students without disabilities who performed below the basic level significantly decreased from 17% in 2005 to 14% in 2015. However, this improvement trend is absent for students with disabilities. In fact, the percentage of students with disabilities who performed below the basic level slightly increased from 43% in 2005 to 45% in 2015. It seems that the gap between students with disabilities and their same-age peers has become wider and certainly does not seem to be closing. In conjunction with this lack of growth in mathematics learning among students with disabilities, expectations for all students, including those with LDM, have been elevated in today's educational climate. In particular, the Common Core State Standards for Mathematics (CCSSM; Common Core State Standards Initiative [CCSSI], 2012) emphasize conceptual understanding of ideas and the connections between mathematical ideas. The CCSSM also emphasizes that students "model with mathematics." In particular, the Common Core emphasizes higher order thinking and reasoning as well as algebra readiness throughout elementary mathematics. The challenge of meeting the expectations of the Common Core Standards is compounded by the shortage of teachers certified to teach mathematics (Hutchison, 2012) and more so, the shortage of special education teachers that is "severe, chronic, and pervasive" and presents threats to the quality of educational services provided to these students (Billingsley & McLeskey, 2004, p. 2). As such, there is a need to explore potential intervention support that addresses the new emphasis of the Common Core to facilitate all students' access to higher order thinking and meeting the standards.
