Decimals
In Year 4 your child moves from fractions into decimals, learning that numbers can carry on past the decimal point. They count in tenths and hundredths, write fractions like a half or a quarter as decimals, see what happens when a number is divided by 10 or 100, and start using decimals in everyday money and measurement. It is an important step that underpins much of the maths to come, from place value to handling pounds and pence with confidence.
Practise Decimals
Have a guess, even if you're not sure. Get one wrong and we'll show you why, so every miss is a chance to learn.
Timed practice
The same practice, just with a gentle clock. Pick a length and see how many you can answer.
The quizzes work through these ideas in small, steady steps, with clear numbers and worked examples where they help. Your child picks an answer from a few choices, and if they get one wrong they see a gentle hint that points them back to the idea rather than simply marking it incorrect. The aim is quiet, regular practice that builds understanding bit by bit, not pressure.
Everything here is free, with no account to set up and nothing to download. It works in any web browser, so your child can practise on a phone, a tablet or a computer, whichever happens to be to hand.
