Lolz the Math Curricula Wars

She's a leftie ;-)

Everyone is competing to show why their textbook/method is "better" for learning math... The truth is every kid probably will prefer a different technique. There are a jillion new "methods" out there these days... Though I will say the old-school tried and true stuff is efficient and effective in most cases.

But this bit of advertising was Quite effective on me... I'd buy it!
