Lego Movie Maker has always been one of my favorite Apps. It is easy to create a custom animation with titles, pictures and sounds. With the built in camera, students can easily take still pictures of whatever they choose to animate.
Recently, I co-taught with a 9th grade ELA teacher that used this App to help his students remember the parts of The Odyssey. He provided a few props relevant to the storyline, a title card with the Episode number, and action cards with the main ideas from the story. This was an excellent process because it kept students on task with a directed plan.
Later, the videos could be watched as a review for an upcoming assessment. The sky is the limit with this App. Give it a try.
