Maureen Spada from Bennett Elementary in Onteora CSD recommends that you check out Word Dynamo.

This is a great addition to your language arts, math, economics, science, history, (ANY) classroom.  Word Dynamo gives students the keys to their own learning by working with them at their own level. It is broken down into Elementary, Middle and High School.

Tip: The Quick Tour will lead you through all the Word Dynamo goodies and have you ready to use it with your students in no time!  Word Dynamo looks and works well on the iPad and iPod Touch browser…great for vocabulary practice anywhere.
