To go with our "scary" unit, 2nd graders read My Father's Dragon by Ruth Stiles Gannett. Rather than read paper books, I asked Actively Learn to set up the book in their interface. I linked some background information, added some notes about different thinking I had as I read, and posed 11 free response questions.
Students read in pairs on iPads. Their response to reading in Actively Learn (their first experience) was that they liked it. Their favorite part was seeing responses from their classmates.
I will definitely use this program more next year, probably with PDFs since there are not many Project Gutenberg books at a 2nd grade reading level that I think will also hold student interest. It was easy to use, easy to see feedback, and ore interactive than the same assignment on paper.
