This happens with my ds too. Same thing happens with whole words sometimes. And math... aagh... happens all the time with numbers!

And checking his work for mistakes.... it's a really good idea in theory, but in practice he usually ends up making more mistakes on the things that were correct to begin with (spelling or numbers)...
