Why Children Should Show Their Working Out in Maths
If you’ve ever heard a teacher say, “Show your working out,” you might wonder why it matters so much. For many children, especially in primary school, it can feel like an unnecessary extra step. But in reality, showing working out in maths is one of the most important habits a child can develop.
It’s not just about getting the right answer—it’s about understanding how to get there.
What does “showing working out” mean?
In simple terms, showing working out means writing down each step used to solve a maths problem. Instead of doing everything in their head, children record their thinking clearly on paper.
This allows teachers, parents, and most importantly the child themselves to see the method behind the answer.
1. It improves understanding of maths concepts
One of the biggest benefits of showing working out is that it strengthens understanding.
A child might arrive at the correct answer, but without showing their steps, it’s impossible to know if they truly understand the method. Writing out each stage helps reinforce key maths concepts such as:
- Addition and subtraction methods
- Multiplication and division strategies
- Fractions, percentages, and problem-solving steps
Over time, this builds a deeper and more secure understanding of maths.
2. It helps identify mistakes quickly
Mistakes are a natural part of learning maths. The key is being able to spot and correct them.
When children show their working out:
- Errors become easier to find
- Misunderstood steps are clear
- Teachers can give more accurate support
Without working out, a wrong answer gives very little information. With it, mistakes become learning opportunities.
3. It builds confidence in maths
Many children struggle with confidence in maths because everything feels unclear or rushed.
Writing down each step slows the process down and makes thinking visible. This helps children feel more in control and less overwhelmed.
Instead of guessing, they can follow a clear path to the answer—and that builds confidence over time.
4. It supports problem-solving skills
As children progress through school, maths becomes more complex. Word problems and multi-step questions require careful thinking.
Showing working out teaches children how to:
- Break problems into smaller steps
- Organise their thinking logically
- Stay focused on the process
These are essential problem-solving skills that go far beyond maths.
5. It prepares children for exams
In SATs and other assessments, children can often gain marks for their method—even if the final answer is incorrect.
This means showing working out can make a real difference to results.
More importantly, it prepares children for secondary school, where clear methods and structured thinking become even more important.
6. It encourages independent learning
Children who regularly show their working out become more independent learners.
They are better able to:
- Check their own work
- Spot errors without help
- Understand where they went wrong
This reduces reliance on others and builds strong learning habits for the future.
Why this habit matters long-term
Showing working out in maths isn’t just a classroom rule—it’s a life skill.
It teaches children to think clearly, organise their ideas, and approach problems step by step. These skills are valuable not only in maths, but in everyday decision-making and future learning.
Final thought
At first, it may feel like extra effort. But over time, showing working out becomes second nature.
And when it does, children move from guessing answers…
to truly understanding them.
If your child is struggling with maths or lacks confidence, encouraging them to show their working out is one of the simplest and most effective steps you can take.
