My kids are still too young for most of the ebooks I got but I found them to be too good to pass up at $1 each! I haven't even downloaded them all yet but I'm enjoying looking at the Teaching Science with Favorite Picture Books. I also enjoyed the 50 Learning Songs to Familiar Tunes. This one is actually at my kids' current level. There are songs about the months of the year, days of the week, life cycle of a frog, etc set to familiar tunes. I also got Read Around the World with 20 Picture and Chapter Books. It has 20 fiction books from different countries along with notes and maps / worksheets to accompany them. Looks interesting! I read someone else's previous post about the Hands on History books being helpful so I snagged the Colonial America, Pioneers, American Revolution, and Explorers of those. We have an iPad so I'm planning on loading these on there and then printing pages as needed (worksheets, etc) rather than printing them all. Thanks for the heads up on this sale! I'm loving it!
