Xtra math is a very unhelpful program that is literally the worst thing to exist. It is used to "help" students memorize facts. I was the smartest kid in my class and could not even get past subtraction because of how horribly designed it is. like there are better programs that teachers could be using so why use Xtra math. I am just saying Xtra math is bad and should be banned from use of education or at least for school use.
