Differentiated instruction is an approach to teaching that aims to meet the varied needs of students. It involves modifying content, process, products, and the learning environment based on student readiness, interests, and learning profiles. This allows teachers to challenge advanced students while also supporting those who need more help. The document outlines strategies for differentiating in elementary classrooms, such as varying reading materials, offering flexible grouping, and providing choice in how students can demonstrate learning. It emphasizes that differentiation works best when focused on high-quality curriculum and ongoing assessment is used to inform instruction. Teachers are advised to gradually implement changes at their own pace with support from colleagues.
