Once again Free Technology 4 Teachers has found an online gem, Word Stash. This is a great site that allows users to "stash" (save) words and create lists. These lists can then be quizzed on. Also, there are a quite a few options to enjoy such as: listening to the word, sharing words via links, viewing examples of the words in sentences, etc etc.
WS can best be described as half a dictionary and half a vocabulary builder.
I highly recommend checking out Word Stash by clicking here!!!
