Be sure to take advantage of all the free stuff first, but consider a "subscription" that gets you into all the password protected pages I have. There you will find hours of instruction and videos that put the theory into practice in real time with real students. 

The best deal is a Lifetime "Sitewide" Pass.

By now it should be pretty clear that you will get a lot more than you pay for considering all the stuff you have already gotten for free...and all the stuff that is being added monthly. The trig page alone (tab marked TRIANGLES) is worth the price of a annual password all by itself...or so I've been told about 100 times now. If you do the math though, the best deal is a lifetime pass, I've even broken it up into 10 easy payments. But before you do that go through the voluminous amount of free material first. 

Bamboo steamer not included. No set of steak knives will be included with your order. Offer void where prohibited. Act now and you any save your child from a world of pain later. 

Whatever you decide, PLAY and have fun. Take the misery out of your math and make learning fun the way it was meant to be.

Note: from time to time the passwords change. Simply e-mail me for a new one or a new passport as the case may be. Annual passes are good for one year, lifetime passes are good for as long as the site remains up, (site has been up for eight years now).  All single page passwords have lifetime renewal.
