For A-Level Economics, I create a narrative for each lesson to keep the student engaged. Economics is more exciting than you think!
I support it with a slide deck for each topic and use it to support the lesson, asking questions and testing the student with mini tasks throughout.
I have a signature blank paper approach for Mathematics, to suit the student's needs. I prefer students to control the lessons to their needs so it is not like another school lesson.
This is by having a blank sheet of paper and the start of every lesson and slowly populate it with notes, this is also tested to be an efficient and effective way to build a mind paradise of content, making it easier to remember.
