Brainpop (there is a website as well as tablet apps) is a wonderful resource for elementary school kids. It covers subjects ranging from Math to Social Studies, Science to English. It uses animation to depict a conversation between a robot and a child. Brainpop jr. features a little girl called "annie". Brainpop features a little boy. The kids answer questions from the robot. The explanations are super clear, and my kids are quite addicted to the app version of this. Highly recommended!
