This is a presentation I made using online presentation tool emaze. If you're fed up with PowerPoint, you should check out emaze - there's a free version with lots of great templates. In fact, I didn't have to do very much to create 'Halloween Fun Facts' - just select the slides, insert the text, and add some creepy music. The result is really impressive (if I do say so myself!).
Click on the arrow symbol (bottom right) to watch the presentation in full screen mode - it's much more effective.
Get your students to use emaze rather than PowerPoint next time they do a presentation in class.
