On the subject of augmented reality, why not have your students create their own set of flashcards using Aurasma. Print out letters for them to colour or have them draw or paint a letter and use it as a trigger. Record a short video of the child talking about things that start with that letter, or showing pictures, or acting out an animal (so many options I won't list them all) and voila!
Of course why stop there? How about having them create their name and link to an iMovie that shows their favourite things.
