🔢 Why decimals matter
Decimals power money, measurement and data — and they're the bridge between fractions and percentages. Children who understand place value deeply find the rest of maths dramatically easier.
🏫 What children learn in Years 4–6
Tenths and hundredths (Y4), decimals to three places, comparing, ordering and rounding (Y5), and calculating with decimals, including all four operations and fraction conversions (Y5–6).
🎯 Built for 11+ preparation
Every lesson highlights the exact traps examiners set — 0.65 vs 0.7, ‘just add a zero’, misaligned decimal points — in a ‘Watch Out!’ section.

Frequently asked questions
What order should my child learn decimals in?
Follow the numbered path on this page: understand what decimals are and place value first, then comparing/ordering/rounding, then calculating, and finally conversions and problem solving. Each lesson builds on the one before.
What ages are these decimals lessons for?
Written for ages 9–11 (Years 5–6 in England) and ideal for 11+ preparation. Tenths and hundredths content also suits confident Year 4 children.
Are these lessons free?
Yes — every lesson and printable cheat sheet is completely free. The MindBlaze app adds daily practice and rewards if your child wants more.
How do decimals connect to fractions?
A decimal is a fraction with 10, 100 or 1000 on the bottom: 0.7 = 7/10. Our Fractions guide pairs perfectly with this topic — we recommend finishing it first.
What is the most common decimal mistake?
Believing 0.65 is bigger than 0.7 because '65 beats 7'. The pad-with-zeros habit taught in lessons D4–D5 fixes it permanently.
