Following a friend's recommendation, I bought the Squeebles spelling app for the iPad recently and Harry did his first list at home. I really like this app. The parent can set up custom lists of any words, with audio recording as well. The child sees and hears the word then spells it using the keyboard. They earn squeebles, which are small creatures, by getting correct answers. I think we will continue to do written spellings but will also be using this for as long as Harry enjoys it. I have set up the next list too, including the ones he got wrong this time.
