If you've never heard of McGraw-Hill Education before, check any educational textbook you've got laying around and chances are it's got their logo on it. They're in the "big three" of educational megacorps responsible for books, computer programs, apps, and all sorts of other educational aids from pre-kindergarten all the way up to post-graduate levels. As anyone who has ever bought anything from a textbook company knows, their stuff is never free. (Far from it, in fact!) Well, today apparently is Digital Learning Day, and they've reduced the price of all their learning games/apps to free.
If you've got an old iPad you let your kids use for Minecraft and YouTube, it's not a bad idea to just grab all of these just so you have them on your iTunes account in case your kids ever feel like learning something. Click here to view their whole iTunes catalog, which mostly consists of math and word games. From the looks of it, individual apps of theirs go free quite often but, this massive freebie sale is all tied to a big Digital Learning Day push they're doing.
Anyway, I think it's pretty cool what a great learning tool iOS devices can be. While this freebie alert likely won't interest everyone, I know we've got at least a few parents who read TouchArcade on the reg'.
Update: I've got no idea what's going on with iTunes today and why people are having problems with these links, but you can just search the App Store for "McGraw-Hill" and see them all. Load up any of them, and then hit the button for other apps by this developer to get the full listing.
