I teach primary school level maths in a fun, engaging way that helps children understand easily

I am 14 and I am trying to fundraise money to cover the costs of travelling to Ghana and volunteering there. I am able to help teach children maths because I know several methods that helped me understand and develop my maths skills. I also currently attend a grammar school, so I have the experience of passing the 11+ maths exam. My sister used to be a maths teacher and has passed on a lot of her techniques and knowledge to me.
