Check out www.spellingcity.com, a free, educational website parents and children can use at home.
I used this website in my classroom for many years. User friendly, kids could independently access and work on their lists at home and at school. They liked being able to choose how to study.
It takes only a few minutes to upload and save a spelling or vocabulary list. When you click on your list, you are given a choice of games to play, puzzles to complete, handwriting sheets to print, etc. Using headphones or a speaker, you can do a test online.
