Mathematics for children from ages 6-11, basic primary maths, multiplication, ect

I am 16, going into college and looking to help children while still being able to do maths regularly all while making some money to add to my university fund. I have always enjoyed maths as someone who is not “gifted” in the subject. And so throughout my time in primary and secondary i picked up many ways to understand maths easier and i would love to help other understand their maths too.
