Google Play for Education

In a recent post, I noted that the Apple App Store has introduced a section specifically for teachers.  Google Play (which is the Android version of the app store) now also has an Education section.  It is not as extensive as what's offered for iOS, but I expect it will grow as more Android tablets hit the market.
Whether it's Apple or Android, though, it seems that many of the education content-specific apps are geared toward K-6.  Take a look at most "top-ten" list of apps for high school students (such as this one), and you'll see that they tend to be "productivity" and "reference" apps.   In other words, while a 4th grade student may be learning math and language arts via an app, a high school student will more likely have a periodic table app, a graphing calculator app, a thesaurus app, etc.  High school students are also more likely to use apps for planning and organization.  The advantage is that many of these apps are used beyond education, so there are excellent choices available, whether on iOS or Android.
