This activity will help you review fractions by looking at clouds and cloud cover. You'll be lead through an activity in class and an online interactive activity called Pie in the Sky.


Watch the movie Clouds to learn about the different types of clouds and cloud cover. Once you have viewed the movie, click on the button "Learn More About Cloud Symbols." These symbols are used to determine and describe the cloud cover in the sky. Now click the arrow button to go back and "Play the Quiz."

Go to the Pie in the Sky activity. This activity looks at other types of cloud cover symbols and fractions. Click on the rocket images to move forward and back through the activity. Throughout this activity, you will be asked some questions about cloud cover. The following information can provide help if you need it.

  • Clear (CLR) -- Sky has no clouds or clouds cover less than 1/10 of the sky. 
  • Scattered (SCT) -- 1/10 to 5/10 or one half of the sky is covered with clouds. 
  • Broken (BKN) -- 5/10 to 9/10 of the sky is covered with clouds. 
  • Overcast (OVC) -- more than 9/10 of the sky is covered with clouds

This esheet is a part of the Measuring Cloud Coverage lesson.
