Click and Reveals are a great way to introduce or review a topic or a unit. The PowerPoint is projected in slide show mode on a screen. Students compete in teams to answer the questions using their resources (book, internet, notes, each other). When they have an answer, they send one member up to the teacher to check accuracy. If the student is correct, they may click the question to begin to reveal a picture. WARNING: Students can get very competitive with this activity! Once all the questions are answered, the teacher can close the slide show and reopen to discuss answers. Students are eager to share their new knowledge with their classmates!
