The second in our series on rounding decimals for year 6, this worksheet looks at rounding to the nearest whole number and to the nearest tenth.
When rounding to the nearest whole number, the crucial digit to look at is the tenths digit. If it is 5 or more then the units will round up; if it is less than 5 the units will remain the same.
When rounding to the nearest tenth the crucial digit to look at is the hundredth.
Difficulties can occur when a number that needs rounding up also changes the units and possibly the tens digits. For example 9.95 rounded up to the nearest tenth is 10.
