This resource is designed for young learners to enhance their reading comprehension by acting as detectives. The core mission is to teach students how to transform reading clues into strong textual evidence through the practice of annotation. It introduces what annotation is and its importance in making important information visible. By annotating, students can leave a ‘trail of breadcrumbs’ of their thoughts, which helps them recall key ideas later. The document also outlines specific investigation symbols for identifying characters and settings in literary texts, encouraging active engagement with the reading material. Students are prompted with detective challenges to deepen their understanding of why annotation is crucial for effective reading and comprehension.
