The document discusses key teaching strategies, including using key questions at the beginning of lessons to engage students in critical thinking. Students work together to answer questions, helping the teacher evaluate learning and the effectiveness of their methods. It also describes a "no hands up" policy where students use traffic light signals to privately indicate their understanding, and are encouraged to pass questions to classmates if unsure rather than raising their hands, ensuring all students actively participate. The overall aim is for every student to achieve lesson objectives without anyone getting left behind.
