Here are two sites which can add variety and interest to spelling activities!
Create words using images from Flickr. Great for writing names or adding interest to spelling words or creating banners to decorate Virtual Classrooms. Type in the word and click on spell. To change the look of a letter click on it. To save the image use can use the snipping tool on your lap top.
This is a great way to add some interest to spelling and integrate geography at the same time. You can type a message and the site finds an image from around the globe which resembles the letter. You could do this as a class activity or send a message to someone.
