Rounding Numbers (Year 5/6)

In KS2 Maths children will look at rounding numbers up or down. In Years Five and Six children should be capable of rounding whole numbers to the nearest ten, hundred or thousand. In addition they will now look at the rounding of decimal numbers and fractions.

Knowing whether to round a number up or down is vital in the world of maths! It very much depends on whether the number is above or below half way. The same rules apply to rounding decimal numbers and whole ones. Just as the whole number 32 is rounded down to 30, the decimal number 3.2 is rounded down to 3. Fractions can also be rounded up or down. For example, ²⁄₅ would be rounded down and ³⁄₅ would be rounded up.
