Teaching your kids to keyboard is a very good way to teach them to spell also. It not only works hand and eye coordination, but they learn to follow the mind.
My favorite book is Spelling Power. It doesn’t take long, and you can really see progress. It is very different than the usual “study a set of words for a week and then have a test on them”. I feel there is a lot less pressure on the kids and they just move on from words they already know how to spell correctly.
