At times it's hard to find resources for children that make sense of Easter, that are biblically sound and which are also engaging. The following resources use animations based on some excellent children's Bibles. I'd encourage you watch them with your children at Easter.
The first resource is a video animation based on Mark 15. The video tells the Easter Story in a simple but accurate way for children. It has been adapted from 'The Jesus Storybook Bible' written by Sally Lloyd-Jones with illustrations by Jago.
The second set of resources are all from the Bible Society in Australia. They consist of one short animation on Jesus' life, two on his crucifixion and then one on his resurrection.
