The children love the Saddleback Kids (www.saddlebackkids.com) and Crossroad Kids (www.crossroadkids.net) websites. They are full of wonderful animated stories and songs telling of God's love and goodness.
Look for Saddleback Kids 'Bible Stories' and Crossroad Kids 'God's Stories' and music videos.
We also use www.request.org.uk which has many fabulous resources for teaching religious education (look at the Re:Quest primary age tab). At the moment we are focusing on the Easter story (Palm Sunday, the Last Supper, the Garden of Gethsemane and Jesus's death and resurrection).
