Fascinating Fact:

Astronomers round the distance from Earth to the Sun to one hundred and fifty million kilometres, because the exact number changes every day.

In 11 Plus Maths, rounding is used to make numbers easier to work with, especially when estimating or checking calculations. Pupils learn to round to the nearest ten, hundred, or even million to simplify complex data.

  • Rounding: Adjusting a number to make it simpler while keeping its value close to the original.
  • Place Value: The position of a digit in a number, which determines its actual value.
  • Estimate: A quick calculation used to get an approximate answer without full accuracy.
What are the basic rules for rounding numbers?

If the digit to the right is five or more, round up. If it is four or less, round down. This rule applies whether you are rounding tens, hundreds, or decimals.

Why do we round numbers in maths?

We round numbers to make them easier to use or compare. It helps estimate totals, check answers quickly, or simplify measurements in everyday problems.

How is rounding used in real life?

Rounding is used in shopping, science, and travel — for example, estimating prices, recording distances, or comparing population sizes without using long numbers.
