# Rounding Starter Questions

## Rounding Practice

Rounding practice worksheets for year 7 and year 8 working at grade 1, 2 and 3. The following rounding worksheets start with rounding to the nearest ten (10), the nearest hundred (100) and the nearest thousand (1000). Rounding worksheet 5 and rounding worksheet 6 round to the nearest whole number and the nearest 1 decimal place respectively. Rounding worksheet 7 and rounding worksheet 8 contain mixed questions on decimal place rounding as well as significant figures. Rounding worksheet 14 onwards contain traditional rounding exercises.

## Number Lines 1 - 10

Number lines can be used to help when rounding. Numbers round down when they are closer to zero and up when they are closer to the next number. Place value and the counting system is understood well before learing how to round. The graph below shows a set of number lines 1 - 10 (one to ten).

## Number Lines 1 - 20

The numbers which are less than zero are called negative numbers. The image below shows a set of number lines 1 - 20 (one to twenty).

## Rounding Chart Nearest Ten

When rounding to the nearest ten we might use a rounding chart. In the rounding chart below the numbers shaded in grey round down. For example, 23 when rounded to the nearest ten rounds down to 20. 74 when rounded to the nearest ten rounds down to 70. The numbers which end in 5, or higher than 5, round up. For example, 19 rounded to the nearest ten is 20. 48 rounded to the nearest ten is 50.

## Rounding Examples

The examples below show the answer when 4.63, 5.75 and 1.98 are rounded to 1 decimal place.

## Rounding Chart Nearest Whole

The graphic below shows a rounding chart to the nearest whole. Numbers which end with .5 (or point five), **round up**. Whereas numbers which end with .4, .3, .2 or .1 **round down**. For example 0.2 rounded to the nearest whole number is zero. 8.4 when rounded to the nearest whole number is 8. 5.7 when rounded to the nearest whole number is 6, and so on.

## How To Round Numbers

The example below demonstrates how to round to the nearest significant figure. When rounding to significant figures we remember that if the number starts with zero then it is not significant. In the example below the first numbers are all significant figures. For harder examples try the Significant Figures Worksheets Page.
