If you have used Clssroomscreen in the past you will remember that they had a polling feature, but the remote polling was only if you paid for an upgrade. With the new version of Classroomscreen, you can now use this feature for free (just need to create a free account).
When you choose the polling feature you will see the options for multiple choice, smileys, as well as True/False. When you choose your poll type you will see options to remove and or add options, choose the poll settings, how to vote, as well as the chart type.
