Educreations (free) is one of my favorite iPad apps. It has recently been updated (Sept 2014), adding features i think will be of good use in classrooms across the school. Educreations can be accessed both on the computer using a web browser and on the iPad. I have used the screen shots i saw on the welcome screen soon after i installed the update on my iPad to explain how it can be used in your class.
The following interactive images act as a tutorial for Educreations explaining the different tools within the app. Hover your mouse over the images (if you are on a computer) or simply touch (if you are on a mobile device) to see descriptions.
I used the thinklink (free) iPad app to create the above interactive images.
