Cars, Fish and Castle
When it all came together we ended up making plasticine characters and 3D paper sets. The children created characters, wrote stories and worked in pairs of three with iPads. It became more than I had imagined because the children's creativity was amazing and so impressive. They seem to have a natural gift for visual story telling.
Because of privacy protection concerns I am unable to post their animated videos. But I can assure you they were all wonderful.
I can recommend a Future Learn Course titled Film Making & Animation In The Classroom for any teachers interested in working in animation with ipads with students.
