Analyzing Line Plots and Data

Mrs. Freiburg introduces third graders to line plots, explaining how to create and analyze them using examples like a spinner and siblings data. Students learn to label, compare, and draw conclusions from line plots through guided and independent practice, enhancing their understanding of data representation.

What materials do you need to learn about line plots?

• A pencil and a math workbook

• A computer and a printer

• A notebook and a pen

• A ruler and a calculator

What is a line plot used for?

• To show how often data values occur

• To calculate the average of numbers

• To draw geometric shapes

• To solve algebraic equations

In the spinner example, how many times was the spinner spun?

• 20 times

• 10 times

• 16 times

• 25 times

What is the first step in creating a line plot?

• Drawing and labeling a number line

• Writing a summary

• Calculating the mean

• Drawing a pie chart

• 6 times

• 7 times

What is the difference between the greatest and least number of X's in the spinner example?

• 6

• 7

• 8
