Why KS2 Maths Matters
KS2 is often called the “make or break” stage for mathematical confidence. Here’s why these four years are so important:
📊 The Impact of KS2 on Future Success
| Area | Impact | Statistics |
|---|---|---|
| Secondary School | Strong KS2 foundation = better GCSE results | Children at “expected standard” in Y6 are 4× more likely to achieve Grade 5+ in GCSE maths |
| STEM Careers | Early confidence shapes subject choices | 78% of engineers report enjoying maths in primary school |
| Life Skills | Practical maths used daily | 92% of everyday tasks require KS2-level maths |
| Confidence | Attitude formed during KS2 persists | Children who struggle in KS2 are 3× more likely to have maths anxiety as adults |
💡 Real Parent Story:
“My son Jacob struggled with times tables in Year 3. We nearly gave up. But with daily 5-minute practice using games, he went from avoiding maths to asking for ‘maths challenges.’ He’s now in Year 5 and loves algebra. The key was making it fun and stress-free.” – Emma, Berkshire
KS2 Maths by Year Group
Let’s break down what your child learns each year, with realistic expectations for each age group.
📘 Year 3 Maths (Ages 7-8)
Key Focus: Building confidence with larger numbers and mastering core arithmetic
What Your Year 3 Child Will Learn
| Topic | Skills Developed | Real-World Example |
|---|---|---|
| Number | Count to 1,000; understand hundreds, tens, ones | “This toy costs £3.50 + £2.25…” |
| Times Tables | Master 2×, 3×, 4×, 5×, 8×, 10× tables | “If 3 friends each have 4 sweets…” |
| Fractions | Understand 1/2, 1/3, 1/4, 2/3, 3/4 | “Cut the pizza into 4 equal slices” |
| Time | Tell time to the nearest minute | “School starts at 8:45” |
| Money | Work with pounds and pence | “Here’s £5, the toy costs £3.20” |
| Shapes | Identify right angles, 2D/3D shapes | “This is a rectangular prism box” |
📝 Example Year 3 Problem
🍕 PIZZA PARTY PROBLEM
Emma has 24 slices of pizza.
She wants to share them equally between 4 friends.
How many slices does each friend get?
YEAR 3 THINKING:
"I know 4 × 6 = 24, so each friend gets 6 slices"
OR
"I can count: 4, 8, 12, 16, 20, 24 - that's 6 jumps of 4"
What Parents Notice
⚠️ Common Struggles:
- Times tables become serious business
- Written methods look different from what parents learned
- Word problems require more thinking
- “I can’t do it!” appears more frequently
✅ What Helps:
- Daily 5-minute times tables practice
- Using real objects (Lego, sweets) to understand fractions
- Patience with new written methods
- Celebrating small wins
📗 Year 4 Maths (Ages 8-9)
Key Focus: Expanding to larger numbers and formal written methods
What Your Year 4 Child Will Learn
| Topic | Skills Developed | Challenge Level |
|---|---|---|
| Number | Work up to 10,000; understand place value | ⭐⭐⭐ |
| Times Tables | Master ALL tables up to 12×12 | ⭐⭐⭐⭐⭐ |
| Written Methods | Column addition/subtraction, grid multiplication | ⭐⭐⭐⭐ |
| Fractions | Equivalent fractions (1/2 = 2/4 = 4/8) | ⭐⭐⭐⭐ |
| Decimals | Understand 0.1, 0.25, 0.5, 0.75 | ⭐⭐⭐⭐ |
| Roman Numerals | Read and write to 100 (C) | ⭐⭐ |
🎯 The Multiplication Tables Check (June, Year 4)
What it is: A government-mandated online test of times tables knowledge Format: 25 questions, 6 seconds per question Pass mark: Typically 20-25 correct (changes yearly)
EXAMPLE MTC QUESTIONS:
━━━━━━━━━━━━━━━━━━━━━━━━
6 × 7 = ?
9 × 4 = ?
12 × 8 = ?
3 × 11 = ?
7 × 8 = ?
━━━━━━━━━━━━━━━━━━━━━━━━
⏱️ Only 6 seconds per answer!
🎓 Teacher Tip:
“The MTC isn’t about tricking children—it’s about building automaticity. If a child has to count on fingers for 6 × 7, they won’t have time. But with regular practice using songs, games, and quick-fire questions, every child can master them.” – Mr. Davies, Year 4 Teacher
📝 Example Year 4 Problem
🛒 SHOPPING CHALLENGE
A shop sells pencils in packs of 6.
Each pack costs £2.40.
How much would 4 packs cost?
YEAR 4 THINKING:
Step 1: 4 × 6 = 24 pencils total (not needed, but good to know)
Step 2: £2.40 × 4
£2 × 4 = £8
40p × 4 = £1.60
£8 + £1.60 = £9.60
ANSWER: £9.60
What Parents Notice
⚠️ Common Struggles:
- Long multiplication looks completely different from parents’ methods
- Decimals are confusing at first
- MTC pressure can cause anxiety
- Equivalent fractions seem abstract
✅ What Helps:
- Daily MTC practice (online games work well)
- Real shopping trips to understand money/decimals
- Using fraction walls or circles to visualize equivalents
- Keeping MTC pressure low-key
📙 Year 5 Maths (Ages 9-10)
Key Focus: Increasingly complex numbers and multi-step problem-solving
What Your Year 5 Child Will Learn
| Topic | Skills Developed | Difficulty Jump |
|---|---|---|
| Number | Up to 1,000,000; negative numbers; square/cube numbers | 🔥🔥🔥 |
| Fractions | Add/subtract with DIFFERENT denominators | 🔥🔥🔥🔥🔥 |
| Decimals | Three decimal places (0.001) | 🔥🔥🔥 |
| Percentages | Understand as “parts per 100”; convert between fractions/decimals/percentages | 🔥🔥🔥🔥 |
| Long Division | Divide 4-digit by 1-digit numbers | 🔥🔥🔥🔥 |
| Angles | Measure and draw angles to 360° | 🔥🔥🔥 |
🧮 The Big Challenge: Different Denominators
This is where many Year 5 students hit a wall:
❌ WHAT DOESN'T WORK:
1/3 + 1/4 = 2/7 (You can't just add tops and bottoms!)
✅ WHAT DOES WORK:
1/3 + 1/4
Step 1: Find common denominator (12)
Step 2: Convert both fractions
1/3 = 4/12
1/4 = 3/12
Step 3: Now add
4/12 + 3/12 = 7/12
VISUAL REPRESENTATION:
[▓▓▓▓░░░░░░░░] 4/12 (same as 1/3)
[▓▓▓░░░░░░░░░] 3/12 (same as 1/4)
[▓▓▓▓▓▓▓░░░░░] 7/12 (combined)
📝 Example Year 5 Problem
🏃 RACE DAY CHALLENGE
Sarah runs 3/4 of a mile on Monday.
On Tuesday, she runs 2/3 of a mile.
How far did she run in total?
YEAR 5 THINKING:
Step 1: Find common denominator for 3/4 and 2/3
Multiples of 4: 4, 8, 12, 16...
Multiples of 3: 3, 6, 9, 12...
Common denominator = 12
Step 2: Convert fractions
3/4 = 9/12 (multiply top and bottom by 3)
2/3 = 8/12 (multiply top and bottom by 4)
Step 3: Add
9/12 + 8/12 = 17/12 = 1 5/12 miles
ANSWER: 1 5/12 miles (or 1.417 miles as a decimal)
📌 Parent Insight:
“Year 5 is when the gap between ‘getting it’ and ‘not getting it’ becomes obvious. My daughter was fine until fractions with different denominators. We went back to basics with pizza slices and building blocks, and suddenly it clicked. Don’t be afraid to go backwards to move forwards.” – Raj, London
What Parents Notice
⚠️ Common Struggles:
- The difficulty jump from Year 4 is significant
- Multi-step problems require planning
- Converting between fractions/decimals/percentages is confusing
- Long division feels overwhelming
- Children either thrive or start falling behind
✅ What Helps:
- Breaking complex problems into steps
- Visual fraction models (bars, circles, pizzas)
- Regular practice with mixed topics
- Checking for understanding, not just correct answers
- Identifying gaps early and addressing them

💡 Success Story:
“My son Leo had a meltdown over times tables in Year 4. We tried everything. Then we found songs on YouTube—now he literally SINGS the 7× table in the shower. Whatever works!” – Michelle, Birmingham
2. 🍰 Fractions, Decimals & Percentages – Three Faces of the Same Thing
This trio causes more confusion than any other area of KS2 maths.
The Big Picture: They’re All the Same!
┌─────────────────────────────────────────────────────────┐
│ UNDERSTANDING THE CONNECTION │
├─────────────────────────────────────────────────────────┤

│ KEY INSIGHT: It's just different ways to write │
│ "parts of a whole" │
│ │
└─────────────────────────────────────────────────────────┘
🧩 Common Misconceptions (And How to Fix Them)
| Misconception | Why It’s Wrong | Correct Understanding |
|---|---|---|
| “3/4 is bigger than 4/5 because 4 is bigger than 3” | Ignores the denominator | 4/5 = 0.8, 3/4 = 0.75, so 4/5 is bigger |
| “0.5 is bigger than 0.25 because 5 is bigger than 25” | Misunderstands place value | 0.5 = 5 tenths; 0.25 = 25 hundredths = 2.5 tenths |
| “You can’t add 1/3 + 1/4” | Thinks you need same denominators initially | You can, but must convert first (7/12) |
📝 Real-World Application
🍕 PIZZA PARTY PROBLEM
You order 2 pizzas for a party.
One pizza is cut into 8 slices (you eat 3 slices).
The other pizza is cut into 4 slices (you eat 1 slice).
How much pizza did you eat in total?
SOLUTION:
Pizza 1: 3/8
Pizza 2: 1/4 = 2/8 (convert to same denominator)
Total: 3/8 + 2/8 = 5/8
REAL-WORLD INSIGHT: You ate more than half a pizza!
(5/8 = 0.625 = 62.5%)
3. ➕➖✖️➗ The Four Operations – Written Methods
Children learn formal written methods for calculations. These look different from methods many parents learned.
Column Addition with Exchanging
EXAMPLE: 3,847 + 2,695
₁ ₁ ₁
3 8 4 7
+ 2 6 9 5
──────────
6 5 4 2
Step-by-step:
1. 7 + 5 = 12 (write 2, carry 1)
2. 4 + 9 + 1 = 14 (write 4, carry 1)
3. 8 + 6 + 1 = 15 (write 5, carry 1)
4. 3 + 2 + 1 = 6
WHY THIS METHOD?
✓ Shows place value understanding
✓ Works for any size numbers
✓ Easy to spot mistakes
Long Multiplication (Grid Method vs Column)
GRID METHOD (Year 4-5):
34 × 26
30 4
┌─────────┬──────┐
20 │ 600 │ 80 │
├─────────┼──────┤
6 │ 180 │ 24 │
└─────────┴──────┘
600 + 80 + 180 + 24 = 884
────────────────────────────────
COLUMN METHOD (Year 5-6):

3 4
× 2 6
─────
2 0 4 (34 × 6)
6 8 0 0 (34 × 20)
────────
8 8 4
👨🏫 Teacher’s Note:
“Parents often say ‘Why don’t they just teach the short method I learned?’ The answer: these methods build understanding of WHAT multiplication actually is. Once children truly understand, they naturally develop shortcuts. Rushing to tricks causes confusion later.”
Long Division – The “Bus Stop” Method
EXAMPLE: 196 ÷ 4
4 9
┌──────
4 │1 9 6
│ ↓
│4 goes into 19 four times (4×4=16)
│19 - 16 = 3
│Bring down the 6
│4 goes into 36 nine times (4×9=36)
│36 - 36 = 0
ANSWER: 49
This looks simple, but Year 6 students do this with 2-digit divisors:
4,235 ÷ 23 = ?
4. 📐 Measurement – Practical Maths for Life
Children learn to measure length, mass, capacity, time, and money—skills they’ll use daily.
Conversion Table (Must-Know by End of Year 6)
| Length | Mass | Capacity | Time |
|---|---|---|---|
| 10mm = 1cm | 1,000mg = 1g | 1,000ml = 1l | 60 sec = 1 min |
| 100cm = 1m | 1,000g = 1kg | 100cl = 1l | 60 min = 1 hour |
| 1,000m = 1km | 1,000kg = 1 tonne | 24 hours = 1 day |
📝 Real-World Measurement Problem
🏡 DIY CHALLENGE
You're painting a bedroom wall that measures 4m wide and 2.5m tall.
One tin of paint covers 5 square meters.
How many tins do you need?
SOLUTION:
Step 1: Calculate area
Area = length × width
Area = 4m × 2.5m = 10 square meters
Step 2: Divide by coverage per tin
10 ÷ 5 = 2 tins
ANSWER: 2 tins of paint
REAL-WORLD TWIST: Always buy slightly more for second coats!
5. 📊 Statistics – Understanding Data
Children learn to create and interpret charts, graphs, and averages.
