Recently there was some excitement over several Android apps that made their way to the Chrome OS store. The four released apps were part of App Runtime for Chrome which is the Chrome Project that brings Android Apps to Chrome OS.
The only released Android App that seemed at all interesting, from my perspective, was Kids Sight Words. Students Join Tammy the frog on a journey through four exciting activities to learn and review 220 Dolch sight words.
The app loads in a constrained window so it can not be resized or maximized. Kids Sight Words was a free app and there were no ads to speak of, which was refreshing.
If you are working with younger students on Chromebooks who need extra sight words practice, Kids Sight Words might be worth a look. My only criticism was the contrained window gave a strong sense of a ported app. It would be nice if future apps had a more natural integration into Chrome OS.
