The document provides guidelines for developing hooks to engage students in learning. It suggests that hooks should be open-ended questions or statements that reference the unit's themes. Hooks can be used before, during, and after a unit to initially prompt students and check their understanding. At the start of a unit, hooks can inspire quick writes or discussions. During a unit, hooks should be prominently displayed to focus learning. At the end, students should deeply engage with the hook by synthesizing and showing their learning.
