To solve the problem of rounding each number to the nearest whole number, we need to follow these steps:
Steps for Rounding to the Nearest Whole Number:
1.
Identify the digit in the tenths place (the first digit after the decimal point).
2.
Apply the rounding rule:
- If the digit in the tenths place is
5 or greater, round up by increasing the whole number part by 1.
- If the digit in the tenths place is
less than 5, round down by keeping the whole number part unchanged.
3.
Drop all digits after the decimal point.
Let's apply this step-by-step to each number in the image.

Explanation:
Each number was rounded based on the value of its tenths place. If the tenths place was 5 or greater, the number was rounded up; otherwise, it was rounded down. This ensures that the result is the nearest whole number.
Parent Tip: Review the logic above to help your child master the concept of rounding to the nearest whole number worksheet.
