Searching for the perfect iPad homeschool apps

Well my search for good homeschooling apps for my new iPad has begun. I had a few apps that I have used before with my iPhone like Google earth and Evernote but now that I have an iPad I have actively begun looking for good iPad apps for homeschooling. I decided to only use iPad apps for now. I am being very selective initially since there are so many apps. I don’t want them to be a distraction. I also don’t want to spend a lot of money on a bunch of new apps.
For the next few weeks I will be searching out the Essential apps for homeschooling.
One of the important tools for homeschooling is a pdf reader. Now I know you can use iBooks but in my experience documents take a long time to load and iBooks is not very helpful if you need to look at a lot of PDFs. So follow the links below as I go through the different apps.
Part one: PDF reader

Part two: Pages
