My brother Steve's math website is Conquest Math, in case you or anyone you know has kids interested in math games. Here's what people are saying about it:
"Shayden loves your math games. He played 3 grade levels for over an hour. He did real well too. Thanks." Jeannie, http://harmonyhaven.wordpress.comSteve says, "Good. If he starts with the first one and goes through them all in any particular grade, he'll get all the math skills for that grade, as listed in California. Pass it along!
If somebody wants the BEST algebra book, they can get my book at www.lulu.com," copied and pasted below:
