The Man Behind Common Core Math
Jason Zimba, one of the writers of the Common Core, waits while his daughters play.
Every Saturday morning at 10 a.m., Jason Zimba begins a math tutoring session for his two young daughters with the same ritual. Claire, 4, draws on a worksheet while Abigail, 7, pulls addition problems written on strips of paper out of an old Kleenex box decorated like a piggy bank.
If she gets the answer "lickety-split," as her dad says, she can check it off. If she doesn't, the problem goes back in the box, to try the following week.
"I would be sleeping in if I weren't frustrated," Zimba says of his Saturday-morning lessons, which he teaches in his pajamas. He feels the math instruction at Abigail's public elementary school in Manhattan is subpar — even after the school switched to the Common Core State Standards.
But Zimba, a mathematician by training, is not just any disgruntled parent. He's one of the guys who wrote the Common Core.
And four years after signing off on the final draft of the standards, he spends his weekends trying to make up for what he considers the lackluster curriculum at his daughter's school, and his weekdays battling the lackluster curriculum and teaching at schools around the country that are struggling to shift to the Common Core.
Zimba and the other writers of the Common Core knew the transition would be tough, but they never imagined conflicts over bad homework would fuel political battles and threaten the very existence of their dream to remodel American education.
When Zimba was first hired to help write a new set of K-12 math standards in 2009, the groups behind the Common Core — including representatives from 48 states — set very ambitious goals. The tough new guidelines would match the expectations set for students in higher-performing rivals like Singapore and South Korea. The standards would not only catapult American students ahead of other developed nations but would also help close the gaps between low-income students in the U.S. and their wealthier counterparts.
The Common Core would drive publishers and test-makers to create better curricula and better tests and push school districts and teachers to aim for excellence, not just basic proficiency, for their students. And the guidelines would arm every principal, teacher and parent with the knowledge of exactly what it takes to get into college and succeed.
The champions of the Common Core — including organizations like the National Governors Association and the Council for Chief State School Officers — expected the task to be difficult. Overhauling textbooks would take a lot of time, and training teachers would take even more. But the bipartisan groundswell of opposition to the standards took them by surprise.
"The creation of the standards is enshrouded in mystery for people," Zimba says. "I wish people understood what a massive process it was, and how many people were involved. It was a lot of work."
As much as supporters emphasize the democratic origin of the standards and count out the dozens of experts and teachers who were consulted, the Common Core math standards were ultimately crafted by three guys whose only goal was to improve the way mathematics is taught. That, some experts argue, is what makes the Common Core better than the standards they've replaced.
"It was a design project, not a political project," says Phil Daro, a former high school algebra teacher who was on the three-man writing team with Zimba and William McCallum, head of the math department at the University of Arizona. "It was not our job to do the politics while we were writing."
But the backlash was perhaps inevitable.
The Inner Circle
On the surface, Zimba, 45, seemed an odd choice for a major national project like Common Core. McCallum and Daro were well-known and admired in the world of math and education. McCallum is a prominent mathematician who has authored algebra and calculus textbooks and helped write Arizona's K-12 math standards. In 2009, Daro was a senior fellow at a for-profit curriculum and teacher-training company, America's Choice. In the 1990s, he was involved in developing California's math standards.
In contrast, Zimba was an obscure physics professor at Bennington, an elite liberal arts college in Vermont. He wrote a quirky math and parenting blog with posts about complex physics problems, his kids, and the occasional political issue, including a 2011 post titled, "Numbers Don't Lie (but Michele Bachmann Does)."
He grew up as an outsider. Raised in a working-class household in suburban Detroit, he was the first in his family to go to college. He chose Williams College in Massachusetts. Academically, the school was a good fit. Financially, it was more of a challenge. His friend Eric Mabery said the two got to know each other because they were the only poor people on campus. "He was the only person who had several jobs," said Mabery, now a biologist at a San Francisco startup. "He was the only other person who couldn't fly home. We had to take the bus."
But from Williams, Zimba's career took off. He was chosen for a Rhodes scholarship to England's Oxford University in 1991. At Oxford, he befriended a Yale student from Manhattan, David Coleman. Coleman went on to become a consultant for McKinsey, the global consulting firm. Zimba returned to Detroit to do stints of factory work to help support his family, but eventually he headed to the prestigious math department at the University of California, Berkeley for a Ph.D. in mathematical physics. In 1999 he reconnected with Coleman, who had an idea for starting an education business.
At first, they considered going into educational video games, but they scrapped the idea in favor of an even bigger educational trend: standardized testing. The No Child Left Behind Act was still around the corner, but a growing education reform movement, which insisted that holding schools more accountable for student test scores would increase performance, had already pushed many states to expand standardized testing.
Coleman and Zimba's business, the Grow Network, found a niche in the burgeoning field of testing by producing reports that helped schools, teachers, parents and even students themselves interpret results from the new exams. "To design a successful assessment report, you need to be thoughtful about what the teacher really needs, what the student really needs," Coleman says.
Thanks to Zimba, Coleman added, they were. Zimba had a genius for creating reports that were mathematically precise but also humanely phrased, Coleman says. Grow Network was hired by states like California and districts like New York City and was eventually bought out by the educational publishing giant McGraw-Hill for an undisclosed price.
Zimba and Coleman went their separate ways. Coleman stayed on a bit longer with the company under McGraw-Hill. After a brief stint at a liberal arts college in Iowa, Zimba landed at
Zimba and Coleman stayed in touch, often discussing a problem that had bothered them during their years studying standardized tests.
"We looked at a lot of standards," Zimba says. "Previous standards ranged from terrible to not good enough. The best of them were little more than test blueprints. They were not a blueprint for learning math."
Every state had its own standards, which varied widely in their expectations for students. For instance, some states required students to memorize the times tables, but about a third of states didn't, according to Zimba.
But what most worried Coleman and Zimba — and many education experts — was the sheer number of standards in most states. The common critique was that most American grade-level guidelines were "a mile wide and an inch deep," in stark contrast to the fewer but more intense expectations in high-achieving countries like Japan and Singapore.
In 2007, Coleman and Zimba wrote a paper for the Carnegie Corp., a foundation with interests in education (and one of the many funders of both The Hechinger Report and NPR). "We were just trying to think about what could really matter in education," Coleman says. "What could actually help? One idea we thought is that standards could be really focused and better. At Grow we'd spent so much time with the endless vast and vague standards."
The paper got the attention of several groups that had latched on to a similar idea, including the Council of Chief State School Officers and the National Governors Association, one of the original leaders of the Reagan-era standards movement. A couple of years later, when the two organizations joined forces to draft a set of "fewer, clearer, higher" standards, Coleman and Zimba were picked to help lead the effort.
The CCSSO contracted with a new organization Zimba and Coleman founded, Student Achievement Partners. It declined to disclose the amount of the contract or the total spent on the development of the Common Core but said funding was provided by the Bill & Melinda Gates Foundation (another supporter of NPR), Carnegie and other foundations, as well as state membership dues from CCSSO and the NGA.
"We were looking for a skill set that was fairly unique," says Chris Minnich, executive director of CCSSO. "We needed individuals that would know the mathematics — Jason and the other writers obviously know the mathematics — but would also be able to work with the states, and a bunch of teachers who would be involved."
Writing The Common Core
In September 2009, Zimba started writing the Common Core math standards. Although his second daughter was due the same month, the standards were all-consuming. Zimba recalled getting a text in the delivery room from one of his co-writers telling him to stop responding to emails about the project: "It's time to be a dad now."
That fall, though, finishing the Common Core math standards came first. He was still on the faculty at Bennington, although on leave for part of the time, so the standards were mostly written at night, in "the barn," an old garage on his property that he had transformed into a study.
"It was hard on us as a family," he says. "I gave an awful lot." In October, his mother, who had worked most of her life as waitress, died. Zimba kept working.
They started with a blueprint that laid out what students should know by the end of high school. It was written by Achieve, a nonprofit founded for the purpose, and by the testing groups College Board and ACT. Then they began consulting the research on math education and enlisting the ideas of experts in various fields of mathematics. During the course of the next year, they consulted with state officials, mathematicians and teachers, including a union group. Draft after draft was passed back and forth over email.
"We'd be up to 3 in the morning," says McCallum. "Jason would be up till 5 in the morning."
The final drafts of the standards were released to the public in June 2010. By the following year, thanks in part to financial incentives dangled by the Obama administration, more than 40 states had adopted them. Zimba quit his job at Bennington to work full time at Student Achievement Partners to promote the standards.
The backlash didn't really begin until 2013 in states like New York, where new Common Core-aligned tests had sent scores plummeting, and Indiana, where conservatives were leery of the Obama administration's support of the standards. It hit the mainstream in early 2014, when a dad in North Carolina posted a convoluted "Common Core" question from his son's second-grade math quiz on Facebook, along with a letter he'd written to the teacher. "I have a Bachelor of Science Degree in Electronics Engineering which included extensive study in differential equations and other high-math applications," he wrote. "Even I cannot explain the Common Core mathematics approach, nor get the answer correct."
Glenn Beck and other conservative pundits picked up the post, and it went viral. A couple of months later, the comedian Louis C.K. complained about his daughter's Common Core math homework on Twitter, and late-night comedians like Stephen Colbert began mocking the standards, too. Critics called the standards too convoluted, too abstract and too conceptual because of the focus on getting students to explain and discuss their answers.
By the summer of 2014, Indiana and Oklahoma had pulled out of the Common Core, other states had passed legislation to replace the standards in the coming years, and still others are threatening to do the same this year. Supporters of the standards, including teachers unions and the Gates Foundation, are now trying to salvage Common Core by calling on states to hold off on the stakes associated with new Common Core tests, including new teacher evaluations in many states based on student scores.
The backlash has both annoyed and baffled the writers. "When I see some of those problems posted on Facebook, I think I would have been mad, too," McCallum says. Daro tells a story about his grandson, who brought home a math worksheet labeled "Common Core," with a copyright date of 1999.
They argue there's actually very little fuzziness to the math in the Common Core. Students have to memorize their times tables by third grade and be able to do the kind of meat-and-potatoes problems Zimba asks of his daughter during their Saturday tutoring sessions, requirements he believes the so-called Common Core curriculum at her school essentially ignored.
Hung-Hsi Wu, a mathematics professor at Berkeley and one of the expert advisers in the Common Core process, blames the Common Core's problems on bad — and ubiquitous — textbooks that the publishing industry is reluctant to change. "Publishers don't want to bother with writing anything because they've gone through too many sets of standards," he says.
And that is the irony of the debate over the standards, and what may be their undoing. As powerful and influential in reshaping American classrooms as the standards could be, they don't include lesson plans, or teaching methods, or alternative strategies for when students don't get it.
Even as Zimba and his colleagues defend the standards against cries of federal overreach, they are helpless when it comes to making sure textbook publishers, test-makers, superintendents, principals and teachers interpret the standards in ways that will actually improve American public education, not make it worse.
Like McCallum, Zimba agrees with the North Carolina dad that the question on his son's Common Core-labeled math quiz was terrible. But as long as Americans hold to the conviction that most of what happens in schools should be kept under the control of states and local communities, the quality of the curriculum is out of his hands. "Like it or not, the standards allow a lot of freedom," he said.
To Triumph Or Die
Zimba gave up an academic career in which he had the freedom to wonder about abstract physics problems in the peace and quiet of his Vermont barn. But, he says, "I'm now participating in a much more urgent problem."
That problem is how to elevate the academic achievement of American students, especially the most disadvantaged, so the country can maintain its competitive advantage in the global economy. These days, Zimba and his colleagues acknowledge better standards aren't enough.
"I used to think if you got the assessments right, it would virtually be enough," he says. "In the No Child Left Behind world, everything follows from the test."
Now, he says, "I think it's curriculum."
This year, Zimba persuaded his daughter's school to try out a new curriculum that's better aligned to the standards he wrote. He is also devoting his time at his nonprofit, Student Achievement Partners, to create checklists other schools can use to find good textbooks that match the Common Core. The group has published training materials, including videos in which teachers demonstrate Common Core lessons.
On a recent rainy afternoon in Manhattan, the organization gathered in a conference room to hash out ideas for an online tool, funded by the Leona M. and Harry B. Helmsley Charitable Trust (also among the many funders of The Hechinger Report), that could help teachers better understand the standards.
One idea for this tool was a "swipe-y" app that teachers could use to figure out whether students grasped a standard or not — something that would function much like Tinder, the matchmaking site. In the end, the group was most enthusiastic about a more low-tech option: a hotline that teachers and parents could call to find out if the Common Core-labeled math problems they found in their textbooks and homework were good or bad.
Daro and McCallum are leading their own efforts. McCallum founded a nonprofit called Illustrative Mathematics that produces sample tasks linked to the Common Core, trains teachers and produces curriculum blueprints. And Daro is actually writing an entire Common Core math curriculum for use on tablets, to be put out next year by educational publisher Pearson.
But it's unclear whether their efforts, and similar ones by like-minded nonprofits and funders like the Gates Foundation, will trickle down to the millions of classroom teachers attempting to adapt to the new standards. Or if the bad curricula still circulating, coupled with the nation's fractured politics, will do them in.
For his part, Zimba is optimistic. "The influence of the tests on the curriculum, it's negative," he says. "They've been a pale imitation of mathematics. I've talked to teachers who say teaching these standards, 'I feel like a teacher again.' That's not going to be easy to take away. Once you taste that, that's powerful."
