I’m going to share some email strings from Utah school board members who are pro-common core, and me, and two mathematicians who are opposed to common core on academic grounds.
Ze’ev Wurman: 2010 California Common Core math validation committee member and former Dept. of Education advisor; opposes Common Core.
James Milgram: Stanford and NASA mathematician; served on official common core validation committe and refused to sign off on the academic legitimacy of the Common Core.
Dr. Milgram wrote (responding to a request for clarification about math standards) in a very recent email:
““I can tell you that my main objection to Core Standards, and the reason I didn’t sign off on them was that they did not match up to international expectations. They were at least 2 years behind the practices in the high achieving countries by 7th grade, and, as a number of people have observed, only require partial understanding of what would be the content of a normal, solid, course in Algebra I or Geometry. Moreover, they cover very little of the content of Algebra II, and none of any higher level course… They will not help our children match up to the students in the top foreign countries when it comes to being hired to top level jobs.“
Tami Pyfer: Utah school board member, pro-common core

Christel – Here is the specific standard that requires students to know how to convert fractions to decimals. (Fractions are rational numbers, perhaps that’s how you missed it in your examination of the standards.) See (d) and also the sample assessment task at the very bottom which asks kids to convert 2/3 to a decimal using long division.
Board members – Feel free to forward this chart along to legislators, constituents, and others asking you about the incorrect claim that we are not going to be teaching kids to convert fractions to decimals. It’s taken from our Utah Core Math Standards documents. I’ve already sent it to everyone who has emailed me about it.
Hope this helps!
TamiDear Tami,In seventh grade?My ten year old fourth grader (home schooled) knows how to convert fractions to decimals and ratios. Does the Utah Common Core recommend this skill be taught only at the level of seventh grade? That seems not very “rigorous.”However, I am happy that it is taught at all. I am glad you found this for me. Thank you.Please look at exhibit B which is on page 26 of this document, as you will see that in the math review of Common Core, by 2010 California Common Core validation committee member and math expert Ze’ev Wurman, Wurman states that Common Core fails to teach many key math skills along with the one we are discussing. I would love to see your review of his complete review to see if these things are taught, and at what grade levels.Perhaps Ze’ev was reviewing the non-integrated math portion of Common Core, which as I understand it, only Utah and Vermont have adopted.ChristelTami,Minutes ago, I forwarded to James Milgram a copy of your email about Common Core math. He served on the official common core validation committee, and would not sign off on the academic legitimacy of these standards. Milgram was also a math professor at Stanford University and a NASA consultant.Dr. Milgram wrote back:“I can tell you that my main objection to Core Standards, and the reason I didn’t sign off on them was that they did not match up to international expectations.

7. NS. 2.d: Convert a rational number to a decimal using long division; know that the decimal form of a rational number terminates in 0s or eventually repeats.
It only obliquely deals with converting a regular fraction to decimal, with a particular focus on the fact that rational fractions repeat. It does not deal with conversion between fractional forms (representations) per se. Further, it doesn’t deal with conversion of decimals to rational fractions, it does not deal with conversion between decimal fractions and percents and vice versa, and it does not deal with conversion of rational fractions to percent and back. In other words, it deals with only one out of 6 possible conversions. It also does it — as you correctly say — too late, and only obliquely at that.
Compare it to the careful work the NCTM Curriculum Focal Points did on this important issue:
Grade 4: Developing an understanding of decimals, including the connections between fractions and decimals Grade 6: Developing an understanding of and fluency with multiplication and division of fractions and decimals … They use the relationship between decimals and fractions, as well as the relationship between finite decimals and whole numbers (i.e., a finite decimal multiplied by an appropriate power of 10 is a whole number), to understand and explain the procedures for multiplying and dividing decimals. Grade 7: In grade 4, students used equivalent fractions to determine the decimal representations of fractions that they could represent with terminating decimals. Students now use division to express any fraction as a decimal, including fractions that they must represent with infinite decimals. They find this method useful when working with proportions, especially those involving percents
(Curriculum Focal Points are available from NCTM for a fee, however you can get them for free here)
Here is what the National Research Council had to say about this issue in it’s Adding It Up influential book:
“Perhaps the deepest translation problem in pre-K to grade 8 mathematics concerns the translation between fractional and decimal representations of rational numbers.” (p. 101, Box 3-9)
“An important part of learning about rational numbers is developing a clear sense of what they are. Children need to learn that rational numbers are numbers in the same way that whole numbers are numbers. For children to use rational numbers to solve problems, they need to learn that the same rational number may be represented in different ways, as a fraction, a decimal, or a percent. Fraction concepts and representations need to be related to those of division, measurement, and ratio. Decimal and fractional representations need to be connected and understood. Building these connections takes extensive experience with rational numbers over a substantial period of time.” (p. 415, emphasis added)
(Adding It Up is here. If you register you can download the book rather than read it online)
And here is what the National Math Advisory Panel said on this issue in its final report:
Table 2: Benchmarks for the Critical Foundations (p. 20) … Fluency With Fractions 1) By the end of Grade 4, students should be able to identify and represent fractions and decimals, and compare them on a number line or with other common representations of fractions and decimals. 2) By the end of Grade 5, students should be proficient with comparing fractions and decimals and common percent, and with the addition and subtraction of fractions and decimals.
The NMAP final report can be found here.
All these important and widely acclaimed documents (by both sides) are quite clear that conversion between fractional representation is a critical component of mathematical fluency in K-8, that it takes time to develop, and that developing it should seriously start by grade 4.
Still wondering about a few basic questions that Judy Park says she will not answer. These are simple! Who will answer them?
1.Where’s the evidence that the standards are legitimized by empirical study– that they have helped, not hurt, kids who’ve been the guinea pigs on Common Core?
2.Where’s the study showing that lessening classic literature helps students?
3.Where’s the study showing that not teaching kids how to convert fractions to decimals helps students?
4.Upon what academic studies are we basing the claims that the common core standards are academically legitimate?
5.What parent or teacher in his/her right mind would approve giving away local control to have standards written in D.C. by the NGA/CCSSO?
–Am I being unreasonable here, or is Judy Park? These are our children. These are our tax dollars. Is it too much to ask to see a legitimate foundation for altering the standards so dramatically?
I can’t answer any of your questions with research data — because I don’t have such data — but I can answer your questions as a teacher and administrator in the Public Education System for 26 years and a mother of 4 and a grandmother of 11 (some of which have been in public school and some in private school and some in home school) and a State School Board Member of 11 years.
1. There is no empirical study of the Common Core Standards — rather they have been vetted by college professors in our state and others, specialists at our State Office of Education and others throughout the nation, other specialists outside the educational community, and patrons, parents and teachers around our state who had a voice in the approval of the Core Standards and their recommendations before they were completely adopted by our State Board of Education some 2 1/2 years ago.
2. There is no study that shows we should lessen the study of classic literature, but there are endless recommendations from universities and the job creators of our nation that our students need to learn to read informational text, as well as classic literature. So my hope is that our students are getting a mix of both, but believe that we need to insure that students can read informational text and understand what it says.
3. There is no study that says that converting decimals to fractions and visa versa isn’t an important part of mathematical study. However, there is a great understanding in the educational field that if we don’t start teaching algebraic and geometric understanding early in public education and expect all students to understand these mathematical facts, as well as fractions and decimals, that we will have students who cannot make it through the mathematical courses necessary to graduate from high school and be ready to go to college. As a high school principal, I had 300 students move into Uintah High from 9th grade that had to take remedial mathematics classes, because they had not passed Pre-algebra. All students need to understand basic algebra and geometric calculations.
4. We have based our faith in the Core Standards, based upon the specialists that created them and support their validity in the educational programs for students. I believe after a couple of years of getting these standards to students, that we are seeing improvement in a deeper set of abilities to process information both in mathematics and English/Language Arts. (Of course my proof are my own grandchildren and what teachers share with me.)
5. Local Teachers and parents don’t know everything about what is quality education — and we did not give away the standards to the federal government or Washington, D.C. — we asked experts in the field, at both the national and states levels of instruction to help develop standards that would help all students be Career and College Ready. The world has changed since we were educated and our students need to know different skills to succeed in the new world of technology and world wide companies.
I am so sorry that you feel so strongly about this issue that you have created such turmoil in our state. We are truly trying to do what is best for our students and if you can pinpoint any Core Standard that you feel is problematic or doesn’t help our students be prepared for college or work, please let me know and I will take it to the experts to see what they think and if they agree we will change the standard.
However, I do not plan to throw out the Common Core, as long as I am a State School Board member, because I believe it is a step in the right direction. I will, however, help correct and update any Standard that we feel needs to be revised.
