This document discusses lead-ins, which are techniques used by teachers to engage students and connect them emotionally and mentally to lesson topics. It emphasizes arousing curiosity and triggering physical sensations. Some advantages of lead-ins mentioned are retaining more memory through sensory activation. Teachers are encouraged to challenge students, understand their existing knowledge, and bring rich sensory experiences into lessons through metaphors, analogies and stories to help students feel the experience rather than just lecturing. Some example lead-in tasks provided include finding soulmates, quizzes, secret alphabets, drawing, miming or explaining.
