I do 1-1 lessons covering both basic and complex numeracy, as well as some algebra and geometry. The amount of time spent on one thing is not fixed, hence if someone needs more or less time on one activity/skill, that is easily accomplished. Content of the lessons will of course change based on age and maths-based competency of the student, so there will always be something that I am able to teach, whether it is the different 2D and 3D shapes or something much more complex, like long division or even quadratics. The possibilities are endless.
