Rounding whole numbers
Round whole numbers to any place value in Grade 6 math using the standard rounding rule — identify the target digit, check the next digit, and round up or keep the same.
Key Concepts
Property When we round a whole number, we are finding another whole number, usually ending in zero, that is close to the number we are rounding.
Examples To round 68 to the nearest ten, we see it is closer to 70 than 60, so it rounds to 70. To round 234 to the nearest hundred, it is much closer to 200 than 300, so it rounds to 200. To round 7500 to the nearest thousand, it is halfway between 7000 and 8000, so we round up to 8000.
Explanation Think of rounding as finding a number's closest 'cool friend' that ends in a zero. For 667, the number line shows 670 is a much closer buddy than 660. If a number like 550 is exactly in the middle, it gets a boost and always rounds up to the bigger, cooler number, 600!
