Today my daughter had an issue carrying five plates from the kitchen onto the dining table

There were five heavy plates in the kitchen and I asked my daughter to carry them onto the dining table. She said they were too heavy so I said to carry half then come back and carry the rest.

“But Daddy, you can’t divide five in half”.

Of course she was right. She couldn’t carry two and a half plates and then come back for the other two and a half.

Luckily she knew what I meant and after finding it really funny, then thinking about it a little longer, I decided I need a few more Ninja Master lessons in the practical application of mathematics in the real world and how language can sometimes be ambiguous, or at least reliant on the other person to “get what you mean” in exactly the same way that computers can’t.

Repetition with variation is very important to help a child secure numeracy in Primary School, here’s why…

Fluency & Numeracy

If you learn how to say “Hello, my name in the Ninja Master” in a foreign language and you say it once, that’s great. If a month later you need to say it, you would probably have forgotten it.

Repeating it with variation on a regular basis helps to not only understand what you’re saying, you will also perfect the accent and work out your own variations – for example “I am the Ninja Master, how are you?”

It’s the same with maths. Repeating how to add, subtract, multiply and divide fractions 300 times gives your child improves their fluency.

Confidence in Maths

The more a child practices how to work out perimeters and areas of irregular shapes the better they will become at is. When opening an exam paper and seeing a few questions about perimeter and area they will immediately feel confident about solving those questions.

Sense Checking their Own Answers in Maths

Practicing percentages for example over and over instills a sense of what is the correct answer. If a child knows how to work out 45% of 700 but has no sense of what the answer should be, they may get the answer wrong and not realise it.

Through repetition a child will sense that 45% of a number is just less than half, so if they’ve worked out that 45% of 700 is 610, they’ll immediately sense this is incorrect because half of 700 is 350. This enables a child to sense and fix their own mistakes.

Not having to waste time in Exams

During an exam a question may require a child works out a long division, e.g. 876 divided by 9. This may only be one step in a six-step question. The child should not spend lots of time trying to remember and work out how to do a long division. It should be automatic.

This is not about learning by rote, it is about making the most essential and necessary maths functions second nature.

I can do this all day…
