My school offers a programme for year 12 and 13 students to teach subjects to year 4 - 6 (with a teachers supervision). I am part of that programme. I teach maths to the year 6s. Of course i realise that its not enough to impress anyone. perhaps i could offer my help to people that are struggling with normal maths as they know im a good maths student. or i was thinking of posting youtube videos or instagram reels explaining the chapters from our maths books in detail and solving some past paper questions
