The document provides a list of over 50 potential lesson starters or activities that teachers can use at the beginning of lessons. Some examples include asking students to identify the "odd one out" from a group, having students rank items in order of importance and justify their answers, setting students scenarios and asking them to respond, and giving students a word or concept to draw without saying what it is for others to guess. The starters are designed to engage students, assess prior knowledge, and introduce the day's topic in an interactive way.
