Key Concepts
- Prepare a line plot to organize the data
Introduction
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 brush is 7 centimeters.
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 object is 4 centimeters.
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 6 centimeters.
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 6 centimeters.
