Number talks are increasingly used in general education mathematics classes to engage students. Yet despite the potential benefits, number talks are given limited attention for students with high-incidence disabilities in special education settings. This article presents special education teachers with both the why and, more important, the how for…

Transition is important to all students but especially important to students with intellectual disability who may need additional supports throughout their vertical transitions in education. This chapter discusses different vertical transitions students with intellectual disability face in education, with particular attention to the movement from…

Fractions are foundational concepts for more advanced mathematics as well as used throughout daily living, for all students, including students with disabilities. This study explored the virtual-abstract (VA) instructional sequence with regard to the acquisition and maintenance of fraction behaviors for three middle school students with mild…

While research exists on parent expectations associated with post-school outcomes of youth with intellectual disability, limited research examines issues of parent--and youth--post-school expectations relative to issues of community, such as living in rural versus urban or suburban settings. Through a secondary analysis of the National…

Virtual manipulatives are an emerging intervention to support students with disabilities in mathematics. Through a multiple probe across participants design, researchers examined use of an intervention package consisting of a virtual manipulative (i.e., the Two-Color Counter app-based manipulative) and the system of least prompts (SLP) to support…

Transition planning is an important element of special education. This study is a secondary data analysis of the National Longitudinal Transition Study 2012 (NLTS 2012) that examined parent, student, and adult service agency involvement in the transition process for secondary students with intellectual disability (ID). The NLTS 2012 is the third…

In theory, both virtual manipulatives and explicit instruction are viable options to support students with disabilities as they learn mathematics. This study explored the effect of a treatment package--an app-based virtual manipulative (Cuisenaire® Rods) in conjunction with explicit instruction--on students' acquisition and generalization of…

Mathematics instruction -- and interventions to support mathematics teaching -- for students with intellectual disability is important yet underexamined. This study explored a graduated instructional sequence referred to as the virtual-representational (VR) as a mathematical intervention. Researchers taught four students with disabilities what…

As K-12 mathematics standards shift toward emphasizing both conceptual and procedural knowledge in secondary courses such as algebra and geometry, the struggles for students with disabilities become more pronounced. To address these challenges, research has commonly explored the use of technology to aid in the teaching of students with…

Employment is an important postschool goal for students with mild intellectual disability; yet, results for this particular population are often not disaggregated from other disability categories. In this study, data from the National Longitudinal Transition Study-2 (NLTS2) were used to explore the extent to which students with mild intellectual…
