I was tired of bomb games, so I made this Harry Potter themed game. The game can fit with any language really, and works well as a production activity at the end of class. Each group of students will need a whiteboard and marker.
As for editing the disappearing words activity: I copied and pasted the background into the front of the slide and then resized it to cover the word. It's not the most elegant solution, but it was easy lol.
The second activity is a spot the difference filler. The kids like it, but just skip it if you don't have time.
The last activity is based on the telepathy game PPT I've seen all over waygook. Just pretend like you're sending telepathic messages to the kids and they'll think its hilarious.
Feel free to edit and reuse anything, and I hope you and your students enjoy :)
