Here is another website that I absolutely love, Www.spellingcity.com. It is a free website where you can sign in and make your own spelling lists. The site needs a teacher account but all the students have to do to gain access is look up the lists by teacher name or you can have them type in the link that takes them directly to your teacher page.
That's the page I use for my kiddos, you can check it out to get a better idea. The site takes your list and generates games the kids can use to practice spelling words. You can also have them take spelling tests through this website and print out the results. It is an amazing site because the kids can access it from anywhere and it doesn't require them to log in. Parents also use it to access each week's spelling words. I LOVE IT!
