Powtoon is an online tool that can be used to make short animation videos.
Most suitable for A1 - C1 level
These animation videos can be used to give a story a bit extra; adding music, having text appear while you are reading it, and introducing animation characters. By turning a text in an animation video, you don't only create a more appealing format, you also have full control of what your audience sees, and when they see it.
Example of an assignment using PowToon:
Write a horror story using an animation video. Keep in mind that it should remain a story (it should contain a written text), but you can use music, background, animations, and other possible elements to build even more suspense...
