Line Plots

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. 

Measure

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. 

Solution: 

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. 

number of inches

Example: 

Measure the length of the object. 

key length

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. 

measure length

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. 

measure length glasses

Solution: 

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

So, the length of the object is 5 inches.
