## Key Concepts

- Prepare a line plot to organize the data

## Measure

We can measure the length of an object.

**Example:**

Measure the length of the object.

**Solution:**

Place the object on a ruler and measure the actual length.

So, the length of the pencil is 2 inches.

### Data

Measure all the lengths of the object and use a table to record that data.

**Example:**

Measure all the lengths of the object and use a table to record that data.

**Solution:**

The lengths of the objects are measured, and the table shows the different lengths of the objects.

We can show the data in a line plot which is shown in the table. Place a dot over the number that shows each length.

**Example:**

Measure the length of the object.

**Solution:**

Place the object on a ruler and measure the actual length.

So, the length of the key is 4 inches.

**Example:**

Measure the length of the object.

**Solution:**

Place the object on a ruler and measure the actual length.

So, the length of the pencil is 9 inches.

**Example:**

Measure the length of the object.

**Solution:**

Place the object on a ruler and measure the actual length.

So, the length of the object is 5 inches.
