This document discusses Universal Design for Learning (UDL), which aims to provide flexible learning opportunities for all students. UDL originated from universal design in architecture and is based on three principles: providing multiple means of representation, action and expression, and engagement. These principles support recognition, strategic, and affective networks in the brain. The document provides examples of how UDL is implemented at Sunset Ridge School, including differentiating instruction and using technology. It also introduces tools from CAST such as the UDL Curriculum Self-Check, UDL Book Builder, and UDL Exchange that could support UDL implementation.
