Spelling is still an important skill though many folks don't actually teach spelling any more. If you are one who still teaches it, have you ever had your kids check out Vocabulary Spelling City? It is free to use and is awesome!!

They even offer training videos.

While the site is free to use, they also have a Premium Membership (really cheap) that comes with extra goodies. I especially like the vocabulary options that come with the Premium Membership.

The site also offers lots of great free resources. This one is a winner.
