Powtoon

 PowToon is Web-based animation software that allows you to quickly and easily create animated presentations with your students by manipulating pre-created objects, imported images, provided music and user created voice-overs. PowToon is used by businesses to create engaging, creative presentations that capture attention, and can be similarly used for educational assessment and content delivery. There is a free version available, as well as paid subscription that allows for more features.
