This app, for $4.99, allows students to create their own animations. Though the app has an associated cost, the web version (http://doink.com) is free. Unfortunately, the web version won't run in Safari on the iPad. Cool regardless.
"Mathtoons Media creates high level math learning tools that use wacky animation, humour and music. The Mathtoons Log App helps students learn how to change between exponential and logarithmic forms of an equation with the animated guidance of Captain Calculator and his assistant, Corporal MiniCalc."
This is a brilliant way for students to be hands-on and take ownership of their own technology. I really like the stop motion animation tutorial at the end of the post.
Shakespeare in bits provides animations as well as the text with reading tools to understand Shakespeare. This one works for Romeo & Juliet, but there are also editions for Macbeth, A Mid Summer's Night Dream, and Hamlet. While it's $14.99, it does come under the VPP so it comes as the same cost as the book.
iNaturalist is a web site, and an app, for sharing pictures and observations of plants and animals. Thanks to Richard Byrne at Free Tech for Teachers for posting!
This is a very cool project where students created their own coral reefs and creatures, combined them via Box, and then animated them in PuppetPals (though it could have been Explain Everything).
