Oodlu is a excellent new (beta) site/app for creating games that I just found out about from Larry Ferlazzo’s blog. The way this works is that an educator signs up for a free account on Oodlu and then add questions to already created games. Then students play the games online or in a free mobile (Google/iOS) app. These games come in a wide variety of styles such as: shooters, breakout, archery, etc. and have high replay value. Best of all, educators and parents can track student progress online or via a parent app to make it easy to differentiate instruction.
I highly recommend checking out Oodlu by clicking here!!!
