This document discusses presentation techniques for teaching English lessons. It defines warmers and lead-ins, noting that warmers are unrelated to the lesson topic and aim to practice fluency, while lead-ins introduce the lesson topic. It also explains the ESA model for lesson structure - "Engagement" to motivate students, "Study" for language practice, and "Activation" to rehearse real-world use. Warmers, lead-ins, and the ESA model provide teachers with techniques for starting lessons effectively and maintaining student interest throughout.
