I confess I have not tried this one, but it was recommended by a reader. ( Thanks A). Apparently this free software is "very similar to Look, cover, write and check for learning spellings, but on the computer. It great for students who likes to learn things on the computer." According to the website "Unlike other spelling programs, the word lists are completely customisable so that they can always match what your child is required to do for school." Review comments include "Simple, research-based, easy for kids to learn & use. Good font size and face for kids. Self correction is built right in." and "You can add your own spelling list. This program is good for kids and adults because it isn't to childish."
