This document discusses strategies for helping students understand what they read across different content areas. It describes several pre-reading activities designed to build students' background knowledge, such as a "Tea Party" where students discuss index cards related to an upcoming text. The document then discusses the importance of activating prior knowledge in three categories: topic knowledge, text structure knowledge, and vocabulary knowledge. It also recommends frontloading strategies where teachers preview texts with students through discussion and modeling their own thinking before reading occurs.
