Addition and Subtraction
By Year 6, children add and subtract large numbers both in their heads and on paper. They use mental strategies for the numbers that suit them and fall back on careful column methods for the rest, building the fluency they will need for the rest of the year.
Practise Addition and Subtraction
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.
This hub also introduces the order of operations, often called BIDMAS, so children know which part of a calculation to do first and can place brackets to change the result. They use estimation to check whether an answer looks sensible, and tackle longer problems that mix addition, subtraction, multiplication and division in several steps.
The questions are multiple choice with instant feedback, and a gentle hint appears whenever an answer needs a nudge. Everything is free, there is no account to set up, and it runs in any web browser on a phone, tablet or computer.
