With permission, I am posting this letter that Dr. David Wright, math professor at BYU, and one of only a couple mathematicians that helped create the A- rated 2007 Utah math standards, wrote to legislators concerning the problems of Common Core implementation from the USOE. We have previously published several posts about significant problems with the USOE math texts.  You can read here about Dr. Jim Milgram’s statement on the low quality of Common Core
