I would be tutoring national 5 maths, higher maths or anything below this level too. I got an A in my national 5, higher and advanced higher maths and am currently studying BEd Primary Teaching with Specialism in Numeracy at the University of Stirling. This course has both modules on education and part of a maths degree so I still use my maths knowledge from school regularly while learning how to effectively lesson plan and about various teaching styles. The national 5 maths course is split into three different units and I have notes, practice questions, practice unit assessments and past paper questions for these. I also have found booster papers and essential skill worksheets that we would work through and talk about in lessons. If there are particular areas you struggle with we can just focus on them but if it is more general help then we can go through everything.
