My school has recently switched to Go Math (or as I like to call it Go Away Math as it's driving us all insane) and one lesson I have this week is on powers of 10 and exponents. I'm surprised at their word form. If I have a base of 5 and an exponent of 4, I have always called this "five to the fourth power." They call it "the fourth power of five." Part of the lesson has the kids writing the word form so I need to teach it to them the way the book has it. Is this normal? I'm much more comfortable saying "ten to the seventh power" rather than "the seventh power of ten" but my book wants me to do it the second way. Looking for insight as to if I'm odd and have been saying it wrong for years and years, if this is something new, or if this is just one more thing that Go Math does differently than all other math I've been exposed to. My hubby (former middle school and high school math teacher) agrees with me and says he's always called it the way I do.
