Regarding Reading Eggspress: not too complicated on the mouse skills - just forward arrows to click on to turn the page. They have books ranging from 5 to 12 years reading level. And then a whole bunch of other stuff, such as grammar. Most of those are timed so we're not doing those yet.
If you can afford it you could sign up the reader for Reading Eggs and he can do reading eggspress - then you'll get reading eggs practically for free. They also have a math program coming soon.
