This is what I am talking about.
I would suggest that you also check out the site http://www.TXTNLRN.com To start learning all you need is a phone no, a text message plan and phone that can send and receive text messages and the desire to learn.
I am passionate about teaching.
BTW, I sent the Math table of two, (as a text message) to two parents and they liked the format. One parent is going to send the message to their child.
