Practice, Repeat & Refine

The Ninja Maths ethos is Practice, Repeat & Refine


It is very important for a child to practice maths ideally every day. Even during a holiday a ninja will exercise to keep their muscles and movements fast and nimble.


A child should solve maths problems over and over again until it becomes second nature. For example example fractions: multiply, divide, add and subtract until it becomes easy. A ninja does not learn a kick then hope to remember it for future use. Once learnt, a ninja will repeat that kick over and over again until it becomes second nature.


A child should aim to improve their maths & moves each time they repeat a type of question. For example: refining how they articulate their working out to get all the marks. A ninja does not tolerate a sloppy kick. Once learnt a ninja will seek to refine even the smallest of imperfections.
