How to Improve Mental Maths Skills in Primary School

Mental maths is one of the most important skills a child can develop during their primary school years. It is not just about answering questions quickly — it is about understanding numbers, thinking logically, and building confidence in problem-solving.

Children with strong mental maths skills often:

• Work more efficiently in lessons
• Feel more confident answering questions
• Perform better in SATs and assessments
• Develop stronger long-term maths ability

However, many children struggle with mental maths. You might notice your child:

• Counting on fingers
• Hesitating before answering
• Avoiding maths altogether
• Lacking confidence when working without written methods

The good news is this: mental maths is a skill that can be taught, practised, and improved with the right approach.

At Prime+ Tutoring, we have helped hundreds of primary students across Milton Keynes build strong mental maths foundations through structured teaching, small group learning, and confidence-focused support.

In this guide, you’ll discover exactly how to improve your child’s mental maths skills — both at home and with expert support.

What Is Mental Maths?

Mental maths is the ability to solve mathematical problems in your head without using written calculations or a calculator.

It includes key skills such as:

• Addition and subtraction
• Multiplication and division
• Number bonds
• Times tables recall
• Estimation and rounding

These skills are essential for success in:

• KS1 and KS2 SATs
• Transition to secondary school
• GCSE Maths later on
• Everyday real-life problem solving

Mental maths acts as the foundation for all future maths learning. Without it, children often struggle when topics become more advanced.

Why Do Children Struggle with Mental Maths?

If your child finds mental maths difficult, they are not alone. In most cases, it is not about ability — it is about gaps in understanding or confidence.

1Weak Number Foundations

If a child does not fully understand number relationships, such as number bonds or place value, mental maths becomes much harder.

2Lack of Confidence

Children who doubt themselves are less likely to attempt answers quickly or accurately.

3Over-Reliance on Written Methods

Some children become dependent on writing everything down, which slows them down and limits flexibility.

4Limited Practice

Mental maths requires regular, consistent practice — not just occasional revision.

5Anxiety Around Maths

Negative experiences can lead to avoidance and low confidence.

At Prime+, we often see students who believe they are “bad at maths” — but with the right support, they quickly improve.

10 Effective Ways to Improve Mental Maths Skills

Here are practical, proven strategies you can start using straight away.

6Master Number Bonds

Number bonds, such as pairs that make 10, 20, or 100, are the building blocks of mental maths.

For example:

• 7 + 3 = 10
• 15 + 5 = 20

When these become automatic, children can solve more complex problems faster.

7Practice Times Tables Daily

Times tables are essential for:

• Division
• Fractions
• Problem-solving

Even 5–10 minutes a day can make a huge difference. At Prime+, we reinforce times tables through repetition, games, and group activities.

8Break Numbers into Smaller Parts

This is known as partitioning.

Example: 47 + 25 can become 40 + 20, then 7 + 5.

This makes calculations easier and builds number sense.

9Use Real-Life Maths

Make maths part of everyday life:

• Shopping totals
• Counting change
• Measuring ingredients

This helps children see maths as useful and practical.

10Play Maths Games

Learning should be engaging.

Try:

• Quick-fire quizzes
• Flashcards
• Online maths games
• Board games involving numbers

In our small group sessions at Prime+, we use interactive activities to keep students motivated and engaged.

11Encourage Estimation

Ask questions like:

• Is that answer about right?
• Is it closer to 50 or 100?

Estimation builds number sense and confidence.

12Use Gentle Timed Challenges

Timed practice can improve speed, but it should be low-pressure.

Keep it:

• Short
• Positive
• Encouraging

13Focus on Understanding, Not Just Speed

Speed improves naturally with understanding.

Avoid rushing your child. Focus on:

• How they got the answer
• Whether they understand the method

14Practice Little and Often

Consistency is key. Ten minutes daily is far more effective than one long session per week.

15Build Confidence Through Praise

Confidence is everything.

Celebrate:

• Effort
• Improvement
• Small wins

At Prime+, confidence-building is at the heart of everything we do.

The Power of Small Group Learning for Mental Maths

One of the most effective ways to improve mental maths is through small group tuition — and this is where Prime+ Tutoring stands out.

Why Small Groups Work So Well

In a small group environment, students benefit from:

• Individual attention
• Learning from peers
• Increased engagement
• Confidence building
• Healthy motivation

At Prime+, we carefully structure our groups to ensure every child feels supported, challenged, and included.

Mental Maths Skills by Age

KS1, Ages 5–7

Focus on:

• Number bonds to 10 and 20
• Simple addition and subtraction
• Counting forwards and backwards
• Basic problem-solving

KS2, Ages 7–11

Focus on:

• Times tables up to 12 × 12
• Division facts
• Fractions and decimals
• Multi-step mental calculations

At Prime+, we ensure students build strong foundations early, so they are fully prepared for SATs and beyond.

Common Mistakes Parents Should Avoid

• Pushing too hard
• Focusing only on speed
• Ignoring gaps in knowledge
• Making maths stressful

Instead, focus on encouragement, consistency, and support.

Why Mental Maths Matters Long-Term

Strong mental maths skills do not just help in primary school — they impact a child’s entire academic journey.

Children with good mental maths:

• Solve problems faster
• Perform better in exams
• Feel more confident in class
• Transition more smoothly to secondary school

It also supports subjects like science, where quick calculations are often required.
