Every class has a Math Number associated with it that guarantees success in it: if you’re in an Algebra 1 class for example, and your Math Number is an 85, you WILL succeed in that class. Guaranteed. If your Math Number is lower than 85, it will be difficult to succeed in the class, EVEN IF YOU’RE TRYING YOUR BEST, simply because you don’t have the foundational skills required to support the new skills you’re being expected to learn. While it’s almost impossible to really and truly thrive in a class who’s Math Number required for success is higher than the Math Number you possess at the time, it is entirely possible to raise your Math Number. That is precisely what a practice-to-mastery method does.
