Percentages: The Complete Guide for Ages 9–11

Everything your child needs to master percentages — 12 short visual lessons, from ‘what does % mean?’ to reverse percentages and exam-style problems. Each lesson takes about 3 minutes, uses hundred-square models, and comes with a printable cheat sheet.

💯 Why percentages matter

Sales, test scores, phone batteries, interest rates — percentages are the most-used maths in adult life. Children who can work with % mentally make better decisions and faster exam progress.

🏫 What children learn in Years 5–6

What percent means and its fraction/decimal equivalents (Y5), then finding percentages of amounts and solving percentage problems (Y6). Our P10–P11 lessons stretch into 11+ territory.

🎯 Built for 11+ preparation

Every lesson flags the traps examiners set — 5% = 0.5, adding successive discounts, dividing by the new amount — in a ‘Watch Out!’ section.

The learning path

Work through the lessons in order — each one builds on the last.

1
What Are Percentages?
Percent means out of 100.
2
Percentages, Fractions and Decimals
Convert between percentages, fractions and decimals both ways, with the key equivalents to memorise.
3
Finding 50%, 25% and 10%
Mental shortcuts for 50%, 25% and 10% of any amount: halve, halve twice, divide by ten.
4
Percentage of an Amount
Find any percentage of any amount by building from 10%, 5% and 1% blocks.
5
Percentage Increase
Increase an amount by a percentage: find the percentage, add it on, sense-check.
6
Percentage Decrease
Decrease an amount by a percentage: find it, subtract it, sense-check.
7
Percentages and Money
Use percentages with money: discounts, tips and comparing deals in pounds.
8
One Number as a Percentage of Another
Turn any score into a percentage: 18 out of 20 = 90%.
9
Comparing with Percentages
Compare scores with different totals fairly by converting to percentages: 17/20 vs 21/25 solved.
10
Percentage Change
Find percentage change: divide the change by the original and convert to %.
11
Reverse Percentages
Work backwards from a sale price to the original: £45 after 25% off = £60 originally.
12
Percentage Problem Solving
Multi-step percentage problems: successive discounts, percentages of percentages, exam-style questions solved.

Frequently asked questions

What order should my child learn percentages in?

Follow the numbered path: understand what % means, master conversions and the 50/25/10 shortcuts, then build any percentage, apply it to increase/decrease and money, and finish with the stretch lessons.

Ages 9–11 (Years 5–6 in England), with two clearly-marked stretch lessons (percentage change and reverse percentages) for 11+ preparation.

Are these lessons free?

Yes — all 12 lessons and printable cheat sheets are completely free. The MindBlaze app adds daily practice and rewards.

Should my child learn fractions and decimals first?

Ideally yes — percentages build directly on both. Our free Fractions and Decimals guides cover everything needed.

What's the single most useful percentage skill?

Finding 10% by dividing by ten, then building other percentages from it: 35% = 3 × 10% + half of 10%. Lessons P3–P4 teach exactly this.
