Toontastic 3D and it is available to download on the Android, iOS, and Chrome platforms. I installed on an Android phone and found it to be easy to use to create animated videos.
To make a video on Toontastic 3D students first select the type of story that they want to create. Their options are "short story" (a three part story), "classic" (a five part story), or "science report." Once they have selected a story type they will be prompted to craft each part of their stories in order. A short description of what each part of the story should do is included before students start each section.
Students can pick from a variety of story setting templates or they can create their own within Toontastic 3D. Once they have established a background setting students then select cartoon characters to use in their stories. Students can choose from a wide array of customizable cartoon characters or they can create their own from scratch. Once characters are placed into the story scenes students can begin recording themselves talking while moving the characters around in each scene. Students can swap characters between scenes, change the appearance of characters between scenes, and move characters from one scene to the next.
To use Toontastic 3D students do not need to have accounts or log into any service. Their completed videos can be saved directly onto the devices that they use to create their videos.
Applications for Education
Toontastic 3D could provide elementary school students with a great way to create videos for a variety of purposes including mini-biographies, retelling of historical events, or to bring the scenes of a favorite book to life in video form.
