Depends on how you want to do it.. I have also blogged about where I started with solo – I often introduce the terminology to the pupils and ensure they understand that its fine to not know something. I also explain that it is a way of helping them understand how to improve their answers. For some pupils I’ve taken 5-6 lessons then looked at the work and helped them understand SOLO by looking at the work they have produced and discussing what level it is at and how we move it forward. Which approach depends on what you are comfortable with.
