Addition and Subtraction
By Year 5, children add and subtract numbers with five and six digits using column methods, including the careful cases where they have to exchange across a zero.
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.
They also add and subtract large numbers mentally using rounding and adjusting, use rounding to check whether an answer is sensible, and solve problems with more than one step.
Our questions mix straight calculation with reasoning and word problems, with a hint on hand whenever it helps. No sign-up.
