In this lesson, we will learn how to measure a pencil to the nearest inch. We'll determine if our pencil is exactly 7 inches long.
An inch is a standard unit of length. It's about the width of your thumb. We use rulers to measure objects in inches. A ruler has long marks for each inch and shorter marks for fractions of an inch.
A ruler has long marks for each inch and shorter marks for fractions. The numbers indicate inch values. When measuring to the nearest inch, we focus on the inch marks, not the fraction marks.
To measure correctly, align the pencil with the ruler. Place the start of the pencil at the zero mark. Keep the pencil straight and read where the end point falls on the ruler.
When reading a measurement, find where the object ends. Identify the nearest inch mark. If the end point falls between two inch marks, we need to decide whether to round up or down.
To round to the nearest inch, look at the halfway point between two inch marks. If the measurement is past the halfway point, round up. If it's before the halfway point, round down. If it's exactly at the halfway point, we round up.
Let's look at some practical examples. A pencil measuring 6.3 inches rounds down to 6 inches. A pencil measuring 6.7 inches rounds up to 7 inches. A pencil measuring 7.5 inches rounds up to 8 inches.
Our pencil measures 6.8 inches. This is past the halfway point between 6 and 7 inches. Therefore, it rounds to 7 inches. Yes, the pencil is 7 inches when measured to the nearest inch.
