Illuminations is always up and running on the web, but now you can take one of its most popular online activities with you when you’re on the go.  Illuminations just released its new, free Android app, Okta’s Rescue.

In this new app, Okta and his friends need your help. Help rescue them by transporting them to a safe ocean. How fast can you transport the Oktas? Use your counting skills to save as many as you can before the timer runs out.

This app was developed for children in grades preK–2 by Illuminations. It is also available as an online activity along with many other free math resources for children at http://illuminations.nctm.org.
