Through hands-on activities aligned to Kindergarten to Grade 3 mathematics standards, participants will explore how cognitive processes, associated with disabilities (including dyslexia and related disorders), impact the learning of whole number addition and subtraction. In this session, participants will build knowledge and understanding of how to utilize the Universal Design for Learning (UDL) framework to proactively identify and address instructional and environmental barriers. Participants will learn how to design instructional supports (including assistive technology) to accommodate the impact of the disability in order to improve student achievement in mathematics. This session was developed by the Inclusion in Texas Network in collaboration with the Texas Education Agency.
