Why Showing Working Out in Maths Matters More as Children Get Older
Many parents feel proud when their child can quickly give a Maths answer in their head. And rightly so. Mental Maths is a brilliant skill. It builds confidence, number sense, and speed.
However, as children move through school, something very important changes. Mental Maths alone is no longer enough. In fact, encouraging your child to show their working out becomes one of the most important habits they can develop.
At Chorlton Tuition Centre, we often tell parents:
“Speed is helpful… but method builds success.”
Let’s explore why this matters so much.
Mental Maths Is A Fantastic Foundation
Being able to calculate mentally helps children:
• Develop strong number confidence
• Build fluency with calculations
• Improve problem-solving speed
• Feel comfortable with numbers in everyday situations
In the early primary years, mental Maths plays a huge role in building understanding. Children learn number bonds, times tables, and basic operations which form the backbone of later learning.
But Maths becomes much more complex as children grow older.
Maths Stops Being About Just The Answer
From Key Stage 2 onwards, Maths increasingly focuses on process, reasoning, and method rather than simply reaching the correct answer.
Children begin working with:
• Multi-step problems
• Fractions, decimals, and percentages
• Algebra
• Ratio and proportion
• Worded problem-solving questions
• GCSE exam questions requiring explanation
At this stage, examiners and teachers are not just looking for the final number. They are looking for evidence that a child understands how they reached it.
Showing Working Out Helps Children Catch Mistakes
One of the biggest benefits of writing methods down is that it allows children to spot errors.
If a child completes everything mentally and reaches the wrong answer, it can be very difficult to see where things went wrong.
When they show their working out:
• They can check each step
• Teachers can identify misunderstandings quickly
• Small errors can be corrected before they become habits
This builds stronger long-term confidence and understanding.
Exams Reward Method Marks
Many parents are surprised to learn that in GCSE and 11+ style exams, children can still gain marks even if the final answer is incorrect.
These are known as method marks.
If a child shows clear steps and correct mathematical thinking, they can often earn valuable marks along the way. Without written working, those marks are simply lost.
Showing working out is not just helpful — it can significantly improve exam results.
Maths Methods Are There For A Reason
Parents sometimes worry that written methods feel slower or more complicated than mental Maths. But structured methods exist to help children tackle larger and more complex problems reliably.
For example:
• Column methods help manage large numbers accurately
• Fraction methods create consistency when operations become complex
• Algebraic steps build logical thinking and clarity
• Problem-solving layouts help children organise information
These methods act like scaffolding. They support children until their understanding becomes secure and flexible.
Showing Working Out Builds Mathematical Thinking
Writing down steps helps children:
• Organise their thoughts
• Break problems into manageable parts
• Develop logical reasoning skills
• Improve accuracy and confidence
• Build independence in learning
These are lifelong learning skills that extend far beyond Maths lessons.
How Parents Can Encourage This At Home
Encouraging working out does not need to feel like pressure. Small supportive habits can make a big difference.
Try saying:
✔ “Can you show me how you worked that out?”
✔ “Talk me through your thinking.”
✔ “Let’s write it down so we can check it together.”
Avoid focusing only on speed or quick answers. Instead, praise effort, method, and clear thinking.
A Balanced Approach Is Best
At Chorlton Tuition Centre, we always encourage a balanced approach.
Mental Maths remains extremely valuable. We actively develop it alongside written methods. The goal is not to replace one with the other, but to ensure children have the full toolkit they need as Maths becomes more demanding.
Supporting Children To Feel Confident In Maths
Many children lose confidence in Maths simply because problems become harder and they do not yet have reliable methods to support them.
Teaching children to show their working out provides structure, reassurance, and clarity. It allows them to tackle challenges step by step rather than feeling overwhelmed.
This is one of the key ways we help students grow in both ability and confidence at Chorlton Tuition Centre.
