I like to use my first lesson with a student devising a joint plan on how the rest of the lessons will proceed. Early on, I will include a lot of images and interactive content- for example putting up images/videos/articles and asking you to write down 5 adjectives to describe it. The next step would then be to put those 5 adjectives into a paragraph in response to a question in a GCSE paper- broadening vocabulary and practicing exam questions has been popular with my students in the past.
