I'm not sure if you've heard of this app but I just love it! The regular app is free or you can buy the edu version for $4.99 which does not allow in app purchases.
It allows you to create an avatar that speaks. You can also use their backgrounds, draw in your own background or import images. Here is the one I made for our class web page.
I'm thinking of using it in the classroom to conduct historical interviews, news broadcasts from far off places and create stories.
I can't wait until the school year starts. My fourth graders will love it.
