My pick ipad back to school apps

I just purchased my teen an ipad. Yes, I am cheap so I bought her a apple store certifies refurbish ipad 1st gen. from the apple store but I did go with a 3g network one. I finally decided that the ipad 1st gen. fit my budget $399 16GB 3G and had a lot of apps she could use while on the bus ride back to the house or staying afterschool  for events. She will be going to high school 45 minutes away, to a private school. So I wanted a portable device that she could use for homework.
After research between android and apple. I liked both but the price won out. I went with a certified  refurbished.  Due to another supposed refurbished item I bought through amazon.com from a non-certified dealer.  After I went to the apple store and they said the item had water damage and the refurbishment was sticking said device in a bag of rice. Luckily it was an amazon.com fulfillment seller and Amazon will accept returns for 30 day after purchase. SO now I go with the company certified refurbished it my cost a little extra $20 –$50  they usually come with a warranty.  The ipad 2 has a few newer features but costs for wifi 16GB $499 and 3G 16GB $629. Purchasing the older generation gave me a $230 savings. Well a savings I then put into for apps and data. Otherwise the ipad2 would have cost with educational and fun apps and the $180 for the year  data package ($15 a month) closer to $850. Where I spent a total of about $600 including the allotted $$$ for data. I have $30 to spend for the year sitting at  Panera drinking a nice refillable coffee, waiting for said teen to finish what ever afterschool activity, maybe even borrow the ipad to surf the web.

Apps  have found I like:
Mental case flashcards $4.99 or  Free classroom edition for teachers and students
Auditorium notes and text $4.99 can't use in the classroom but reading notes and text book out load  creates great notes. Though if daring could run on ipod or phone in pocket in class??
My teens lowest subject math I found mestudying : algebra 1 hope it helps the Florida virtual school uses this app:

Cramberry website and app $3.99
coursesmart free ??? not sure of yet but could be helpful
iworks at $30 a little  $$$ but worth it compatible with microsoft also. You can get a 30 day free trial to try it out. I think it should be on the pad to begin with as part of the software.

Well since I am an art teacher I had to go over a few new art apps that I found:My favorite and I am going to need to borrow my teens ipad a few times a year for class is brushes they do gave an iphone/pod version but it is best on ipad just because for kids the screen is larger.  I have 3 ipods and 2 iphones that I can use in class. SO have decided to add this to my art lessons this year. I am going to mention it to administration about allowing students to bring in their own ipod/phones but we do have a policy so I’m not sure if it would be ok’d or not.
