Apps for a 2nd Grade Teacher's iPad

My wife just rejoined the teaching ranks. Upon her induction, she received an iPad. She promptly asked me if I would add any apps to it that I thought a 2nd grade teacher might use. Um...sure!

Here are screenshots of the apps that I downloaded for her. They are mostly in alphabetical order. My wife already gave a thumbs up to Mo Willem's Pigeon app, which she used with her students during a transition.

Would you have downloaded any additional apps on this iPad?
