As a long time math teacher with first year iPad experience, I find myself still using some drill and practice for certain math concepts. I have been able to use some of the old math drill and practice problems by photocopying them on our copier. Instead of paper, I choose email option and email the pdf to myself. I then download the pdf attachment and upload it to Google Docs.
This provides the option for me to create a publishing URL and post it to our blog.
See the process...
