The high principal, Mr. Strand, attended the TIES conference also. At one of his sessions he got the great site about iPads with learning objectives. This site lists 19 leaning objectives for the iPad and when you click on that objective, it brings you to a list of apps that help you accomplish this objective. A really neat site with direct links to learning objectives:)!
Good luck with this - again - SO much information - but take a peek as you might find one thing that was worth it:)
**I will be posting later a little more about QR codes:)**
