I've been teaching geography across the age groups (7-13) in Essex for the past 9 years. I'm currently the head of department at my school. The lessons I include in my shop are all in one lessons. Each lesson ppt have a starter, differentiated learning activities, handouts and a plenary. Once you purchase a lesson you don't need to do much before you teach it. My lessons have a variety of activities but they all follow a simply straightforward structure.
