Thing 4 has decided that it's time she learn some keyboarding skills. Unsure of where to start, I consulted my homeschool network and one of my homeschooling friends directed me to Dance Mat Typing. Thing 4 loves it! She has learned a lot already. I love it, too, because it's another one of those self-paced, self-directed activities which allows me time to work one-on-one with her brother on another subject.
I think it's more appealing to the younger set than it would be to older kids. If you have a younger child who needs to learn to type, check it out!
