Understanding Rounding
What is Rounding?
Rounding is the process of adjusting a number to make it simpler but keeping its value close to what it was. It often involves increasing or decreasing a number based on the digits that follow it.
Why is Rounding Important?
Rounding plays a crucial role in mathematics and everyday life. Some key reasons include:
- Simplifies calculations: Rounding makes mental math easier. 🎉
- Estimation: It helps in quickly estimating costs, distances, or measurements.
- Data presentation: Rounding can make data easier to read and understand.
Rounding Rules
Rounding to the Nearest 10
When rounding to the nearest 10, you look at the digit in the ones place:
- If the digit is 0, 1, 2, 3, or 4, round down.
- If the digit is 5, 6, 7, 8, or 9, round up.
Example:
- 32 → 30 (rounded down)
- 47 → 50 (rounded up)
Rounding to the Nearest 100
When rounding to the nearest 100, you need to consider the digits in the tens and ones places:
- If the last two digits (tens and ones) are 00, 01, 02, 03, 04, 05, 06, 07, 08, or 09, round down to the lower hundred.
- If the last two digits are 10, 20, 30, 40, 50, 60, 70, 80, or 90, round up to the higher hundred.
Example:
- 247 → 200 (rounded down)
- 753 → 800 (rounded up)
Practicing Rounding with Worksheets
