Yes! You can present any Deck or Vocabulary List (when you sign in with a Google account) to an unlimited number of times to any group.
When you create a Deck (a slide presentation) or a Vocabulary List, the file is stored in either your Google Drive if you login with a Google account, or your OneDrive if you login with a Microsoft 365 account. You can open it, edit it, and present it as much as you like. Each time your present the Deck or List and collect responses, this information is automatically saved as its own Session, which you can review later in your Sessions menu. Here are the ways to present a file again:
When you're done presenting a List, simply close the browser window. When you are done presenting a Deck, click the END button. Or, click the More Actions (three-dots) button on the Navigation Bar and select End This Session.
Now you can name this Session. A Session is a single presentation of a Deck that contains the student responses you collected. Like Decks, Sessions are saved automatically - but they're easier to find if you name them.
All Sessions are saved automatically in your Pear Deck Home Sessions menu.
